Edits in the angular code not reflected in the local installation

As an beginner in Angular, I wanted to try making some small changes to the minds front-end (local host), but no matter what changes i make to the HTML files in src/app/.. the changes are not being reflected on my local install of minds, even after performing sync-engine and sync-front. Changes to the PHP files in engine seems to work well when using this methodology. I have tried clearing the browser cache as well.

Is there a different method/process to making changes in the front end ?

I have tried renaming Discovery, adding small HTML codes in app.component.html, etc. The changes are not reflected in the browser on reloading. I even tried adding a comment, but couldn't find it in inspect. Previously i had tried a direct ng serve from front folder, didn't work out, so I realised the entire minds website needs to be loaded on localhost. @benhayward.ben , Please, a little bit of guidance here if possible.
