I follow this process:

• In the build.gradle.kts I change the applicationId and namespace to the new name
• If the folder is showling com.example.name and you can only edit the "name" word, tap on the options menu on the riht side of the left pane and then appearance / diselect compact middle package, and now you can edit the "example" word separately from the "name" word
• Clean and sync the project again
