oauth2 or oidc module for FreeRADIUS

[Việt Đức Trần]

Hi Everyone!
I am using FreeRADIUS version 3.2.1 installed on Ubuntu server 22.04 and I
need to make a connection from my FreeRADIUS server to an external
authentication server by using OAuth2 or OpenID Connect protocol.
But I cannot find any available FreeRADIUS modules for OAuth2 or OpenID
Connect.
If these modules currently don't exist or do not support FreeRADIUS 3.2.1,
how can I make the connection from my FreeRADIUS server to external
authentication server via OAuth2/OIDC protocol?
Thank you so much for your help./
