Qt6 on arm

Idk if this is the right forum but has flatpak kde platform/sdk been discontinued for arm ? flatpak install flathub org.kde.Platform/arm/6.2 - doesn't work

Last version that it worked was 5.14. I found a workaround for 5.15 but I can't apply the same for qt6. Arm is still a pretty popular platform, lots of raspi distros still use it. Thanks !
