How to login using Azure AD grant type as authorization code

[Amitm11]

Recently my organization shifted the login authorization flow from keycloak to Azure AD using Authorization Code. I am having hard time getting the code and then from that code getting the access token to authorize the user login. Following are the parameters used
client_id
tanent_id
grant_type = authorization_code
scope
redirect_url

It would be of a great help to get the solution ASAP.

Thanks,
Amit
