How to reverse block local file access setting?

On postman mac 7.36.0:
I was once able to post files from my Desktop folder.
Today I was challenged if I wanted Postman to access it and accidentally denied access - a reflex action to any unexpected ‘grant me access’ dialog.
Now I am getting “Error: form-data: EPERM: operation not permitted, open '/Users/…/Desktop/…” when I try to post.
Nothing in the settings seems to affect it. Tried changing working directory to Desktop but now Postman just crashes every time I try to post.

Nevermind - on a hunch I found the blocker in the mac Security & Privacy Preferences under Files and Folders. Grant access, then restart Postman.
