Hello fellows,
I’m going to write some random input bits and anwers.
First of all, so to actually be everyone on the same page:
sudo dnf --refresh upgrade om-welcome
If you are uncertain, on top of your comment please post the ouput of
rpm -q om-welcome
To debug om-welcome please run command from console
om-welcome
and look at what is going on.
Copy/paste the output to the testing report if any issue occurs.
If it’s very long, use pastebin or a pastebin-alike service and provide the link.
In the latest 2.9.2-1 version (cooker and rolling) is included a new feature to install Brave Browser along with its repo straight away with just one click.
So far internal testing succeeded. But we are here to test more widely, aren’t we? 
Just noticed a minor (?) issue where it may or may not work at first attempt. Click on the same module again should properly work. This is being investigated.
