How to create the "Buy in 1 click" functionality in Bitrix?

Question

1C-Bitrix

You need to add a "order in 1 click" button, which calls the form with the "phone" field, and the result of the form is adding an element to the new "Quick Orders" iblock.
I have not worked with web forms in Bitrix before. So I realized that I need to create a form with the same name, add a question asking me to enter a phone number, and what is the next procedure?

There were free modules on the marketplace. You can take a look at how it's done.
