Setting up form submission tracking via CSS selector

In this video, I will explain how to set up tracking for the "Call you back?" form submission from the toy website. But it doesn't matter which site, what's important is to technically understand how to do it. Specifically, in this case, I am setting up tracking through a CSS selector. In fact, there are many different options for tracking forms. First, you need to check how the form works, and then decide how to set up the tracking. Sometimes not everything is visible in the video; for some reason, the screen recording doesn't capture everything. If you need to set up tracking for form submissions - message me privately.
