I have a very simple form with two questions;
Category (dropdown list)
- cat01
- cat02
- cat03
Attachment (file upload)
When the form is submitted I am using a flow to generate an approval, this works as expected. See image of current working flow.

After the approval is true, I want to save the attachment to a specific folder in my OneDrive. e.g.
if ms form category == cat01 then save to My Docs/stuff/cat01
if ms form category == cat02 then save to My Docs/stuff/cat02
if ms form category == cat03 then save to My Docs/stuff/cat03
I am using OneDrive for business.
How can I achieve this?
