How to connect google e-commerce to google ads?

Question

Google

Good afternoon, dear forum participants,
Perhaps an easy question, but it was not quickly resolved.
Essence: I plan to launch campaigns through google ads. The site is configured with google analytics e-commerce via google tag. How will it be correct to set up conversion tracking, conditionally spent so much on budgets and so many purchases happened?
Has anyone experienced this setup? I will be grateful for advice. Intuitively, I can't find a way without creating new tags, and using only existing ones.
Sincerely,
Vladislav
