Permission problems when exporting to Markdown

What I did:

Selected a project, selected Share, selected Save As File, selected Markdown, selected “As separate files”

What happened:

A macOS (13.4.1 (c) ) warning shows up:

You don’t have permission to save the file “My work logs” in the folder “Agenda Exports”.
To view or change permissions, select the item in the Finder and choose File > Get Info.

The folder “My work” was created, but there are files in it. “Get Info” shows that I can read and write here. I do not have problems to store files in any other app on this macbook.

What I expected:

files being in the folder

Things that might be helpful to know (Agenda version, OS and model, etc):

    macOS 13.4.1 (c) (22F770820d), Version 17.0.2 (271) - Mac App Store

BTW, exporting as a single file works as expected

Unfortunately this is a known issue caused by the sandbox Agenda is placed in, what usually works is to export to your downloads or desktop folder instead when you get this error.
