How to configure VNC to persistent mode in Tumbleweed, Xfce desktop?

I am using Tumbleweed with Xfce desktop environment. I enabled Remote Administration Settings (VNC) to Allow Remote Administration With Session Management and then I can connect to the computer by port 5901 with TigerVNC from other computers. The only problem is I don’t know how to make the session permanent. I tried to run vncmanager-controller from terminal in a VNC session but it shows: VNC not managed by vncmanager, quitting. I tried to find vncmanager.conf from the whole system but it …

Out of ideas

Thank You in advance.
