If you stack with Hotwire official video from hotwire.dev?

Tried yesterday hotwire with rails 7.4.3 abd I had some issues there.
Following official video tutorial by running commands like:
rails new chat --skip-javascript

gem 'hotwire-rails'

rails hotwire:install

I started to get console error:
You must either be running with node (package.json) or importmap-rails (config/importmap.rb) to use this gem.

Solution was to add missing importmap's by:

./bin/bundle add importmap-rails
./bin/rails importmap:install

After that final command was successful:
rails hotwire:install
