Can we send/submit forms?

Yes! There are different ways to approach submitting forms.

1. POST requests. The simplest way for non-secured endpoints is to send a POST request as the page does. Just look at the requests on the browser DevTools and try replicating them.
2. Imitate the user behavior using Javascript Instructions. You can visit pages protected by antibot solutions and then interact with them. Fill in inputs and click on buttons, plus any other action you can think of.
