How to configure popup form call via #bitrixform link?

Question

Bitrix24

Friends, do not consider it stupid, but I'm tired of it ... and there is no answer anywhere.
There is a contact collection form that is called by clicking on the text We will call you back
The code that generates cms
We will call you back

It is required to change the code so that the form is called from anywhere where I attach the link, and as I understand it, the link should be made like #leadform
Please help.
