How to prefill automatically in the form field from the parent value?

Hi All!

I am using a sample by AppSheet - CRM (https://bityl.co/7N2g).

In this one, I don’t want to select any company from the list. The contact field in the form (Step 4) gets filled automatically with the name. I want the same to be done for the Company as well.

How can I do it please?
