Desktop mode won't let me change icons, says no write access to .local

Your system information

• SteamOS version: 3.6.20

Please describe your issue in as much detail as possible:

In desktop mode in the favourites menu, if one wants to change an icon, it won't save the chosen icon. It pops up an error dialog saying:
"Could not save properties due to insufficient write access to: '/home/deck/.local/share/applications/org.flatpakappname.desktop'."

Steps for reproducing this issue:

1. Right click on an icon in favourites, select edit application, click on an icon, choose an icon, press ok, try to apply it.

I feel that the home folder SHOULD have write access to allow people to change the icons.. why are the .desktop files write protected???
