How to configure snap version of neovim?

Hi. Pretty much the title.
I’m trying to recreate my setup (configs, using a snap version of neovim (–beta for 0.5), but:

  1. Normal configs don’t work, since snapd isolates everything.
  2. Due to snap’s limitations, there’s no way to lift the isolation, unless the package is published with --devmode.
  3. Neovim 0.5 has no plugs for any interfaces at all, so I can’t pass the normal user configs there.
  4. Files in ~/snap/nvim/current are ignored.
    The distro is Rocky Linux, if it somehow matters.
    I was told there that I should ask here.
