Role based access from Azure AD groups in asp.net core applicaton

I am having one asp.net core web applicaton, in which authentication is happening from Azure Active Directory Microsoft authentication. There are 2 AAD groups one is admin and another one is user group. for admin group there is a button should be enabled and user group bit should be disabled. That is already implemented and working fine in local solution. After hosting in azure and accessing the web url from Azure roles are not picking and it is not working. need some help to resolve this issue in azure to pick the user roles from AAD groups.
