Inactive submit button untill required field filled in

Hi webflow fellows.

Is there a way I can make my submit button inactive until the required field is filled in?
I looked through the forum and therer were a couple of requests on this one, but no clear decision…

The reason I need it, is the analytic tool counts clicks on the submit button as submissions, even if the form is not filled in. If the button is active only when for example phone input is filled in, then I will count only actual submissions.

I mean I know this can be easily done in code, but I am not a coder. Is there a piece of code for that anyone could share and tell me how to build it into my project so it works?
