RoboHelp 2019 - TFS connection with specified user account

How do we connect to TFS and specify a user account and password for the connection? It looks like RoboHelp is trying to use the currently logged in user account and does not give an option to provide another user account instead. Due to this limitation we are unable to connect to our TFS server. We have many contracted developers with their own computers that are not joined to our domain. They have domain accounts and could provide those to RoboHelp, if RoboHelp would allow for this. Anyone has such an issue? Do you know if there's any workaround for this? We are on version 2019.0.7. I posted a feature request to Adobe. Here the link:
