Your implementation is solid, but you forgot to properly integrate bootstrap5
;-)
The official documentation states:
Make sure to include Bootstrap’s CSS and JS. Insert the tag in the for
our CSS, and the tag for our JavaScript bundle (which includes
Popper for dropdown positioning, poppers, and tooltips) before the
closing </body>

You also have the option to add Popper and our JS separately. If dropdowns, popovers, or tooltips are not in use,
you can save some space by excluding Popper.
