Open note externally does not work on Flatpak builds

[CrO2Cl2]

Trilium Version

0.63.5

What operating system are you using?

Other Linux

What is your setup?

Local + server sync

Operating System Version

Zorin OS 17.1

Description

Since I remember using Trilium on the flathub build, the "open note externally" feature has never worked. This is probably because of the permissions the flatpak has.

If it is not possible to give the flatpak the permissions to use this feature, we should at least tell the user that this feature is not available for the flatpak, so that the user does not think that this is a problem on their side.

I can confirm this happens locally with the v0.91.6 as well.
However I can see the following error being output in the console:

and it being printed twice is not a copy/paste mistake :-)

FWIW, I have made "Open Note Externally" work on 0.63.7 by running it like so:

TMPDIR=$(mktemp -d)

flatpak run --filesystem=$TMPDIR --env=TMPDIR=$TMPDIR com.github.zadam.trilium
