"Copy Field Values from one Module to another" how to use?

"Copy Field Values from one Module to another" how to use?

Hi everyone! I'm sorry if this question was already asked, I didn't find it!

So let me explain:  In my Tickets module, we have the custome field "customer type" where we indicate if it's a lead, user, etc... In the Contact module I used the "type" field with exactely the same entries. I would like when in the tickets module an operator choose an option that it automatically update it in the contact module.

I found the "Copy Field Values from one Module to another" custom function which seems perfect for my needs. But to be honnest, I'm not an expert and I couldn't understand the 5 fields (OrgId/FromFieldValue/PasteInModule/EntityIdToUpdate/ToFieldName) or how I should set it up. Please find attached a sreenshot of the custom function i'm talking about

Did someone used it?  so we can finally automatize it...
Thank you for your help!
