ADFS with Groups

I have LDAP logins from AD working great.
Since it also pulls in the AD groups for each user, I can create a shared account for each group, allow access to the AD group and then any new users in that group automatically have access to that shared folder when they log in.

What I’d now like to do is process logins via our ADFS environment. Is there any way to tie these two together?
User logs in via ADFS/SAML, Nextcloud then grabs the user’s groups via LDAP/AD and I can achieve the same thing?
It seems right now an ADFS user and a LDAP user are separate entities.

Any help would be much appreciated!
