The problem isn't that GNOME devs are trying to make user friendly software for non-technical users; that intent is commendable. The problem is the GNOME devs have incredibly insulting opinions about the skills and intelligence of non-technical users.
You can't even change language shortcut from default (Win + Space). As I understand this comes from MacOS, which gnome devs brainlessly copy.

I do find Gnome plenty configurable. You just need to go in order of Settings -> Tweaks -> their weird registry -> custom extensions. I would agree this is convoluted, but I do not mind it (as a power user it took me 5 minutes to google how to do it, while it probably makes sense to have only the first state (Settings) visible by default).

IT'S NOT CONFIGURABLE. You can hack your way around their "opinionated defaults" which are for MacOS user from USA.
Take a look at the KDE's settings for this case https://i.stack.imgur.com/ukKmp.png
There is no reason to google, install some tool and mess with it.
At least in the recent versions I've tested, you literally can't. You can only set it to an image.
