How can I exclude a file from Zed's recent projects list

[MaddyGuthridge]

I work as a software engineering teacher and am considering switching my primary editor to Zed. When I mark students' work, I'll often need to open tens of temporary directories in my editor over the course of a few hours. After this, clearing my recent projects history is quite a chore. In VS Code I had to create a script to filter them by accessing an SQLite database, which was complex but manageable.

How can I remove items from Zed's history (or prevent them from being added there in the first place)?

• Ideally, I'd want to open a directory using zed --no-history /tmp/directory or something similar
• But instructions for how to access Zed's history in a database are also acceptable for my needs

Thanks :)
