Hit Windows key + r to open the run dialog, type:
explorer "%AppData%\Opera Software\Opera GX Stable\_side_profiles"
and press enter to open the side profiles folder.
In the side profiles folder will be the folder for each exsiting Opera GX side profile.
So, if you see the folder 31313730385F31393735353335323936 in there, then you'll want to create a shortcut with a side profile command that uses that ID.
So, you'd right-click on your desktop, goto "New", choose "shortcut", type:
"C:\Users\yourusername\AppData\Local\Programs\Opera GX\launcher.exe" --side-profile-name=31313730385F31393735353335323936 --with-feature:side-profiles --no-default-browser-check --disable-usage-statistics-question
(replace yourusername with the name of your user folder as seen in "C:\Users".)
in the "location for the item" field, click next, name the shortcut what you want, and click "Finish".
Then, once the shortcut is created, right-click it, goto "properties", click "Change icon" on the "Shortcut" tab and point it to the "On the side.ico" that's in the "_side_profiles\31313730385F31393735353335323936" folder.
