Is there any rule on what consent to the processing of personal data should look like?

Question

Law in IT

Hello!
Tell me, is there any clear form for obtaining consent to the processing of personal data?
An example is accepting applications, where the client indicates his Name and Phone, do I definitely need a block with text, where it says that he agrees to all this if he clicks send?
And if so, does it have to have a strictly defined text and design, or is the presence of text in the adjacent block sufficient?
