    WARNING: Action Text can't locate your JavaScript bundle to add its package dependencies.

    Add these lines to any bundles:

    require("trix")
    require("@rails/actiontext")

    Alternatively, install and setup the webpacker gem then rerun `bin/rails action_text:install`
    to have these dependencies added automatically.
