multitenant-saas-guidance | guidance project for implementing multi | Azure library

I have a console application that I use for authenticating the user and then calling a web API. I am using this Microsoft library for acquiring token, active-directory-dotnetcore-devicecodeflow-v2, I registered both of my console application and API in Azure AD and gave the permissions and role needed based on this doc : GitHub readme, so I have permissions like below in my console app registration in Azure.

Now when I add the new scope "http://{domain}/Migratory.API/api.access" in the list of scopes and call the "AcquireATokenFromCacheOrDeviceCodeFlowAsync" method , there are some conflicts :

If I call the method for the first time, it would call the "GetTokenForWebApiUsingDeviceCodeFlowAsync" and the result does not contain my scope, it contains only the "User.Read , User.ReadBasic.All, All profile openid email", but if I call the method again, this time it would call the "AcquireTokenSilent" method and this one only has the "http://{domain}/Migratory.API/api.access" in scopes .As a result it would generate two different tokens which I don't understand why.

Any idea how should I fix this or where I am doing wrong? thanks
