Git authentication in Studio

Hi all,

How does Stoplight Studio authenticate to the git repo we can use to start a new project ?
I’ve just create a new private Github project on our Actito HQ Github account to validate how to work with Studio, I’ve been able to create a new project (Desktop version) but I’m unable to commit any change (Repo Not Found it says : 37 )
Seems that Studio uses OAuth to connect to my Github project and I’ve granted access to that repo to the Stoplight OAuth :

But in the Developer Tools window I’ve got 404 Not Found on those calls too :

Thank you for your support !
