How to update a contact ?

Hi,

I have a flow which :
- When a new contact is created
- Create a parent folder in my google drive
- Create a shared folder inside the parent folder 

Then, I want to update my contact with the Parent folder link and the shared fold link in 2 fields.

But, when I choose "Create or Update a Contact" in Zoho Flow, it always create a new contact, the flow is triggered and it's an infinity loop hahah.

How to target the right contact ?

Thank you very much :) !
