Cannot share a single file to app if it is recreated after app startup

There was a post on this forum that is somewhat similar to this issue, but it did not receive a response.

File Permissions allowing one file to be created in home directory

Hi, I tried the following perms: –filesystem=~/.app.cfg –filesystem=xdg-documents and they work…as long as ~/.app.cfg already exists. If it does not, the file ~/.app.cfg does not get created and the write fails. Note that the application chooses that name prefixed with a dot. Any ideas on how to allow it to be created? The ‘:create’ suffix does not work…it creates a DIRECTORY named .app.cfg. Thanks, Patrick
