Firefox, apparmor, home folder

Ubuntu 22.04 with Firefox snap. I would like to access rust documentation: ${HOME}/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/doc/** but apparmor locks me out of home folder.

I can modify /var/lib/snapd/apparmor/profiles/snap.firefox.firefox adding above folder to snap.firefox.firefox profile, but it does not survive snap refresh.

What is approved way to permanently adjust apparmor rules for firefox snap?
