E21: Cannot make changes, 'modifiable' is off

[MuhammadSawalhy]

When I moved into the popup by pressing <leader>gm twice, I tried to use o to navigate backwards in the history of messages, but it seems that o tries to add a new line.

Can you show how to reproduce it with list of the steps?

1. Open Vim with some file vim foo.txt
2. <leader>gm
3. ...

return {
  'rhysd/git-messenger.vim',
  dev = true, -- clone the repo to your dev folder (specified in your lazy config)
}

I use the lazy package manager (neovim).

As a workaround, I used a local version of the plugin and remapped the o key . source
