Update a Deal Stage after a Contact Update from Forms

Update a Deal Stage after a Contact Update from Forms

Hello,

I have a business flow I need to configure on Zoho CRM but I'm stuck. I tried workflows (partially successfully) and now I'm trying Flows for the first time (completely stuck).

Maybe the experts out there can help me:

Business Flow:
  1. We will send an email template to a Contact with a Zoho Forms link for him/her upload extra documents
  2. The Form is integrated to Contacts, so the the documents will be saved in the Contact's Attachments
  3. After the form is submitted, a task is created to our team member to assess the extra documents
  4. At the same time, we need the Deal related to that Contact to have its Stage changed from A to B (in the pipeline) - All the previous steps (1, 2, 3) are working fine through Forms - CRM - Workflow, but I couldn't figure out a way to make the step 4 work.
I don't code, so I'm trying to find a codeless solution, if possible.

Thank you very much,

Paulo
