Answer 1

Accually i solved the problem. I faced the problem becouse of version of bootstrap. i used bootsrap 4.3 to make the project, but when i add popover feature, i take bootstrap v5 popover. Thats way, in the popover button is not showing.

Solution : Use same version of bootstrap for popover.
