Problems with custom components in Aurora

Hi!
I have two questions about new custom components in Aurora communities.
In documentation:
Create a pull request to pull these changes into the main branch of your plugin (<phase>-main, not main). The pull request must be merged
We merged our changes to stage-main branch, but this changes are not appearing in the community ( stage-main is the active branch in the community)The added ExampleComponent does not appear in the list of Custom Components, but when I change the branch to feat/cleanup-package-lock (merged branch), the changes become available.
