Ubuntu arm64: element and onlyOffice

Hi,
I am new to flathub and I am having problems installing element and OnlyOffice on ubuntu 22.04 arm64. I was able to install other flathub software. I think the packages are not available for this architecture.
Do you have any suggestions?
Thank you

it’s not available for this architecture.

Element has just added support for arm64. So I expect to have a build soon.
Thanks
