Peertube + Azure auth

Hello,

I was wondering if this is good forum to ask, but I am struggling with setting up the SAML2 + Azure. Documentation for the plugin is kinda dead annd code is stale for 8 months (-> peertube-plugin-auth-saml2 · master · Framasoft / PeerTube / official-plugins · GitLab (framagit.org)

I have setup many Azure auth apps in the past and this one is just not working, I am getting errors « SAML responce is not valid for this audience ». Google gives nothing, again - documentation for Peertube/plugin returns nothing as well. Can I get any help please?
