Radio Button Required Field
Hello Community
I have multiple questions on an adobe form that are radio button.
Three fields, Yes, No, If yes explain
How can I make this whole question a required field, but not require "If yes", when no is selected. Here is the example:

I have seen answers posted but they tend to be a tad confusing. I am not well versed in scripting. And which goes where. I am using Adobe Acrobat Cloud version I know how to add the script just need to know if required or read only need to be checked for each and what script goes with which button
What script goes in "Group1" yes?
What Script goes in "Group1" no?
What Script goes in "If yes"?
Thank you
