We have multiple Abp Applications lets call them client apps and we have one of the abp io application lets call it SSO provider which is responsible for managing our users and authenticate user for client applications (Working as Identity provider in the ecosystem) We are Building a mobile app using react native that will use different apis from these client ABP Applications, in the mobile app user will login with our SSO provider to interact with client application API For this we have managed to authenticate the user with our Identity provider abp app and able to receive an id and access token in mobile client upon login. Now the next step is I believe is to exchange that token with client application to login the user and receive client application access token which we can use for authentication and authorization in the client api I believe the endpoint to exchange that application token is clientapp.com/api/identity/external-login in swagger there is no details mentioned about the input parameters of this api endpoint. Can you please guide?
