RDP Gateway topics

Hello!

I am trying out our companys central RDM database on Linux client version. As we use RDP gateway on 99.9% of our connections, I have run into some troubles and questions.

1) Where exactly are those "my RD Gateway credentials" configured? I cannot find a place for them.

2) When I open that Credentials button, I get this screen:

Why is credential repository grayed out?
(expected behaviour: like on Windows, the stored credential logic opens, we store them in the same vault as our connection info)

3) not exactly RDP Gateway question, but almost connected. We use Delinea Secret Server (previously Thycotic) for all our credential management and the "credential selection" options and logic differ between Windows and Linux versions, making it currently impossible to use the same connection on both platforms. Is there any ongoing development in that section?

4) reading your forum I found an opinion that "Automatically detect RD gateway settings" and "Do not use the RD Gateway" probably have the same result on Linux (which makes sense). Why not remove the auto option from Linux version?

Thanks in advance!
