Remap of Windows key

[stygge-ulv]

I use Ubuntu 22.04 with the lates .deb file from here, and tried to do a remapping af the windows key (Multikey) to Super_L. However Super_L is not part of the keys in the pulldown menu that can be mapped to it seems, but Super_R is there however. What i want is to map Multi_key (Windows Key) to Super_L - i.e. from keycode 133 to 206 (seen from "xev -event keyboard" command). But it seems it is not possible. Maybe I missed something ? Help would be appreciated. The result is the same in Ubuntu Xorg and Wayland.

I can add that i found a file in ~/.config/input-remapper/xmodmap.json which contained all code mappings. It missed one entry for keycode 206 so I added one line with Super_L and keycode 206. But when i started input-remapper then it changed it right back.

I noticed that the keycodes printed when using "input-remapper-gtk" and "xev -event keyboard" are NOT identical. Thus, when I hit the windows key i get a keycode 125 (Multikey) in input-remapper-gtk, whereas I get a keycode 133 from xev. When i use "xmodmap ~/.Xmodmap" to do a manual remapping, then I get the right result so I can use Gnome keyboard shortcuts with the Windos key as intended.
The contents of ~/.Xmodmap (which is working as desired when done manually , but is not persistent over logins) is the following:

remove mod4 = Super_L
clear mod3
keycode 0x85 = Super_L 
add mod3 = Super_L

in order to make it work I had to remove mod4 mapping which had already grabbed the Super_L :

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Caps_Lock (0x42)
control     Control_L (0x25),  Control_R (0x69)
mod1        Alt_L (0x40),  Meta_L (0xcd)
mod2        Num_Lock (0x4d)
mod3      
mod4        Super_R (0x86),  Super_L (0xce),  Hyper_L (0xcf)
mod5        ISO_Level3_Shift (0x5c),  Mode_switch (0xcb)

Maybe the problem is caused by the Super_L is already grabbed by some earlier key mapping somewhere. So is there a method in input-remapper to first remove the default mapping of Super_L, and then re-assign it to Multikey ?

It is strange why "input-remapper-gtk" and "xev -event keyboard" gives different values for the keykodes of the windows key - and different values for the mapping to Super_L for the two methods ? Is there anyone who can explain this ?

I have found another solution using "setxkbmap" insted and put it in a Gnome autostart .desktop file. It works fine except when i disconnect/reconnect the keyboard, and have to do it manually again.
