GitHub sync from repository to TestProject

Hello community,

I can synchronise TestProject project to Github repository that’s awesome! When I modify my test in TestProject tool, my test in my repo is updated → it’ great!
But in the other way, from my repo to TestProject tool in cloud, there is no synchronisation.
Have you done it? if yes, how do you do it?
Likewise, if a colleague pulls my TestProject project , he can’t open it with TestProject.

Do you tips to help me please?
