You are working on an existing project that is connected to a GIT version control...

The Push option is used to provide local versions of files to the remote repository in a GIT version control system. Pushing is the process of uploading local repository updates to a remote repository. By pushing changes, other users who have access to the remote repository can view and collaborate on the project1. To push changes to a remote repository, the project must be committed locally first, and then the Push option can be selected from the context menu in UiPath Studio2. References: Pushing changes to a remote repository and Managing Projects with GIT from UiPath documentation.
