Bootstrap5 collapsible navbar not working in mobile view

Question

I am working with Bootstrap 5 Navigation bar's collapse button functionality in Angular 11. It works fine in desktop site but not in mobile view. One reason I am thinking is that I don't have popper.js installed in the app. Do I need popper.js with Bootstrap5(angular.json file given below)?
