io.elementary.Platform is installed with multiple versions and taking enormous size of memory

[OmarShawky1]

I was freeing up disk from memory and I found out that flatpak is taking much space especially io.elementary.Platform as it is installed with multiple versions. Should I safely remove everyone except 6.1 because I am on Hera 6.1?
This is the output from flatpak:

$ flatpak list --all --show-details

You should be able to run flatpak uninstall --unused and it will uninstall ones that are not used by any applications.
