Problem with rebuilding/reloading extension changes

Hi,
I removed the new extension, and SuiteCRM is working again.

However, we’re back to step 1.
When I make any changes to the defaultExt component in ‘sidebar-widget.component.html’ or the account page ‘detailviewdefs.php,’ nothing updates on the SuiteCRM site.

I tried this command after making changes:
yarn run build:common
yarn run build:core
yarn run build:shell
yarn build:defaultExt
composer install
