Which recaptcha? Using Gravity forms with Elementor

Both Gravity forms and Elementor both offer Recaptcha in their settings. Elementor offers both v 2 and v3. Do these work in tandem? Do I need to put the keys/secrets in both spots?
Should I only use Recaptcha 2 because gravity forms only uses v2?

Just looking for what the optimal setup is here.

Thanks in advance.
