How to make a pop-up form with CRUD in angular 9?

Hi all,

I have made a pop-up form in a table . On the clicking of add button on the top right of the table the modal opens with details to fill . On filling the details in the form and clicking save button of the modal I need to perform CRUD. Where add ,delete and update needs to be performed ,so that the form details are added to the table . Which can be further deleted or updated.

My problem is that I don’t know how to perform CRUD because I am very new to angular.Also I am not supposed to use angular material table or jquery.I don’t need an API it’s just basic CRUD. I have used html ,css,bootstrap and angular. Can you provide me with a link or video that solves my problem.
