Command already exists

Relevant code: https://github.com/simrat39/desktop-notify.nvim/blob/5519667934520468e2a9da3979055091b46dfeec/plugin/desktop_notify.vim#L1

Error:

E174: Command already exists: add ! to replace it: Notifications :lua require('desktop-notify').open_history()

This occurs when using something like rcarriga/nvim-notify, which defines a command with the same name.
