@AleTorrisi can you check on this? Looks like the import isn't finding the js component. Does this PR also need to update the staging module?

[AleTorrisi]

@circlecube It works fine but it's required use the PR newfold-labs/wp-module-staging#92 that has been already merged in the main branch.

I've made the changes in the #1094 branch/PR since it looks like we still need a staging module release to accommodate staging updates in all brand plugins.
