Flatpak for ARM64 Linux

[ell1e]

Is your suggestion related to a problem? Please describe.
I am trying to run a matrix client on a PinePhone.

Describe the solution you'd like
flatpak element. while that exists, it is only packaged for x64 right now.

Describe alternatives you've considered
Using a different client might work, but many lack an ARM64 option. Web login also, but it's a bit fiddly since none of the web browsers on the PinePhone have a good UI.

Additional context
related to element-hq/element-desktop#656 except that one appears to be kind of focused on the x64 side of things

The flatpak is unofficial, you ought to reach out to its maintainers. #15227 is about an official ARM/64 image.

@t3chguy I'm asking for an official ARM64 flatpak image though, not docker. (I believe these are packaged differently, even though they are obviously both containerization technologies.) So I'm not sure #15227 is related, however I can put this into a comment on element-hq/element-desktop#656 if you want me to

[t3chguy]

Yeah comment on element-hq/element-desktop#656 would be sane, but it'd likely be much quicker to reach out to the party maintaining the existing flatpak.
