Send a Zoho form to obtain documents to attach to the "attachments" section of a profile

Send a Zoho form to obtain documents to attach to the "attachments" section of a profile

Hello,
I am very new to the Zoho platform but do have some background in programming in general.  I don't think I've quite understood the flow and platform yet enough to answer my question.

I would like to create a form (web form?  zoho creator app?; something I can send to select clients by email, say) that prompts customers I send it to, to attach specific documents that when submitted will attach to the "attachments" section of the client's profile. 

Something like..

Attach document 1 here  <Attach field>
Attach document 2 here <Attach field>
---------------------------------------------------------------
which when submitted attaches those docs to the customer's profile.  Am I making sense?  Is this possible?

I would appreciate any help or guidance. 

p.s. I have made the form I need through the Zoho Creator app but I"m not sure how to share it or tell it to send the responses to the attachments section.
