Google Tag Manager Not Firing "form_submit" Event for Submit Button

I'm using a form on a landing page for Google Ads campaigns, and I'm setting up tracking with Google Tag Manager. I need help with two things:

1) How to change the form ID to create a specific trigger?
2) The submit button doesn't fire the "form_submit" event in Google Tag Manager. Is there a way to fix this?

It fires the "form_start" event, but not the "form_submit" event. Google Tag Manager validates using the "type=submit" attribute. Is it possible to include this?
