'Default access token' doesn't seem to allow link previews at all

Hi

I want to enable link previews in Nextcloud documents for Github issues that are in private repositories.

I don't wish for my Nextcloud users to connect their own Github accounts to their Nextcloud accounts via OAuth.

I created a personal access token (the 'beta' kind, with finely scoped Read-Only access to: code, discussions, issues, metadata, and pull requests

I added that PAT to the global administrative settings in Nextcloud under settings/admin/connected-accounts as the 'Default access token'.

I ticked the box 'Enable Github link previews'

I still get 'Github API error Not Found' widgets appear in my documents when I paste a link to a Github issue in a private repository that this Github user has access to. The widget wants me to go to my personal account settings in Nextcloud to configure Github access, but I thought the 'default' access token should take care of it.

What's the problem? Is it the beta 'fine-grained' PAT method? I don't want to use the Classic method because I don't want Nextcloud to have write access to private repos through this token.

Otherwise, what are the scopes required for the PAT to work, with the beta method?

Do I still have to set up an OAuth2.0 app even though my use case is limited to link previews?

I am running Nextcloud 25.0.8, Github integration app 1.0.15

Commencez par le flux settings/admin/connected-accounts et le paramètre « Enable Github link previews », puis reproduisez la réponse Not Found avec un token en lecture seule à granularité fine sur Nextcloud 25.0.8 et l’application d’intégration GitHub 1.0.15. Le travail est terminé lorsqu’il est déterminé si le token par défaut est pris en charge pour les aperçus d’issues privées, que les scopes requis ou l’exigence OAuth sont identifiés, et que le comportement est documenté ou corrigé.
