How to register new options in the "open in dropdown"

[lindalinya]

How can I register/custom the options in the "Open in dropdown"?

After I installed the fork, I installed some other software, such as cursor, vscode, etc., but they are not displayed in the open in drop-down box, and I wonder if there is any way for me to customize the dropdown options?
