Recaptcha v2 and v3 what are S data and Action?

I’m trying to get recaptcha to work for the first time and any help is appreciated. I want to use these blocks but there seem to be parameters that are not documented (Or I’m just not looking in the right place?)

if you can help me out feel free to reach out to me.

The S data parameter is not required, only sometimes when there is an s-data attribute in the HTML tag.
