How to force adding PermissionDefinitionProvider only after the user is authenticated? #5799

• ABP Framework version: v7.0.1
• UI Type: Angular
• Database System: EF Core (Oracle)
• Auth Server Separated

I have custom Permission Definition Provider:

    using AbxEps.CT.Core.Extensions;
    using AbxEps.CT.Core.Localization;
    using AbxEps.CT.Core.PortalMenu;
    using Microsoft.Extensions.DependencyInjection;
    using System;
    using System.Threading.Tasks;
    using Volo.Abp.Authorization.Permissions;
    using Volo.Abp.Localization;
    using Volo.Abp.Threading;
    using Volo.Abp.Users;

    namespace AbxEps.CT.Core.Permissions
    {
        public class CorePermissionDefinitionProvider : PermissionDefinitionProvider
        {
            private readonly ICurrentUser _currentUser;
            private readonly IAbxPortalsMenuAppService _abxPortalsMenuAppService;
    
            public CorePermissionDefinitionProvider
            (
                IAbxPortalsMenuAppService abxPortalsMenuAppService,
                ICurrentUser currentUser
             )
            {
                _abxPortalsMenuAppService = abxPortalsMenuAppService;
                _currentUser = currentUser;
            }
    
            public override void Define(IPermissionDefinitionContext context)
            {
                var coreCtGroup = context.AddGroup(CorePermissions.GroupName, L("Permission:Core"));
                var fileMngPermission = coreCtGroup.AddPermission(CorePermissions.FileManager.Read, L("Permission:FileManager:Read"));
                fileMngPermission.AddChild(CorePermissions.FileManager.Modify, L("Permission:FileManager:Modify"));
                if (_currentUser.IsAuthenticated)
                {
                    AsyncHelper.RunSync(() => InitPortalAccessPermissionsAsync(context)); // Not called, because when the host is started the user is still not authenticated - so "if" condition is not invoked
                }
            }
    
            private async Task InitPortalAccessPermissionsAsync(IPermissionDefinitionContext context)
            {
                ...
            }
        }
    }
        

Whereas the permissions which are supposed to be added unconditionally (fileMngPermissions) are added successfully when host is running, the permissions which need to be added only after the user is authenticated (portalAccessPermissions) are obviously not added and not visible via IPermissionAppService:

    var allPermissionsForRole = await _permissionAppService.GetAsync("R", "Role 1");
    

How to add a whole CorePermissionDefinitionProvider or the part of its relevant permissions (portalAccessPermissions) conditionally - once the user got authenticated?

P.S. I'd prefer not to use Middleware, because its Invoke method is invoked on each request. Instead, I need to add my CorePermissionDefinitionProvider or its authentication-related permissions once after the user authentication was successful. I use external authentication via Identity Server. So this functionality needs to reside inside the application project, not Identity Server project.

Making PermissionDefinitionManager a ITransientDependency (or probably I can make CorePermissionDefinitionProvider transient too) does not sound good either: I dot not want to trigger the check each time. I just need to trigger it ONCE, but after the user has been authenticated.
