During a migration from gitswarm to gitlab we lost all of the projects avatar. I'm trying to restore them via a python script, but while it is clear how to set the path of the avatar via the project settings API, I do not understand how to upload the avatar. I searched the GitLab API documentation, but I was not able to find anything. Can someone help me please?
PS: GitLab API: upload projects avatar is of no help, since nobody explained the upload command
