Error using "Custom icons" for Authenticator: 'Unhandled Exception: PathNotFoundException: Creation of temporary directory failed, path = '/tmp/user/1000' on icon pack load

I'm trying to load a Custom icons pack. This failes, regardless of the pack.

~  flatpak run com.yubico.yubioath
…

Nota bene: Using the application "Flatseal" and manually allowing access to the aforementioned directory fixes the error.

App has no access to this path so manual override by user is right workaround for this.

You can put those icons in ~/.var/app/com.yubico.yubioath/data so app could access them in normal way.
