"AADSTS650057 : Invalid Resource" error HTTP with Azure AD to a custom app (Azure App Proxy)

I am getting the following error when trying to connect the "HTTP with Azure AD" step:


Failed with error: 'AADSTS650057: Invalid resource. The client has requested access to a resource which is not listed in the requested permissions in the client's application registration. Client app ID: 7ab7862c-4c57-491e-8a45-d52a7e023983(App Service). Resource value from request: https://<internal-address> Resource app ID: <my app id>. List of valid resources from app registration: . '. Please sign in again or choose another connection.


This app is an Azure App Proxy to an internal API, protected with Azure AD login. I have gone into Azure Active Directory's App Registrations and made sure under 'API Permissions' it has:
Azure Active Directory Graph: User.Read

ServerAppName: user_impersonation, User.Read


I have looked for 7ab7862c-4c57-491e-8a45-d52a7e023983 in the API permissions but can't find it.

Anybody an idea how to configure this connector?

I want to use it in combination with a API Management
