Thank you @Fox
Marked as solved and Credits in the topic :)
So I went to registration FORM and I clicked the button submit to register then BAS detected that it uses RECAPTCHA v3.
So I set the recaptcha v3 settings to this
then I put this before the button.
now when I clicked the register BUTTON all it does is SPIN SPIN SPIN and I noticed on HTTP Sniffer that no DATA is being sent to 2captcha api?
please help?
