How do I disable the built-in context menu and use a third party one?

[zenwav]

I'm on Windows and trying to use tsl0922/mpv-menu-plugin as my only context menu in mpv, but I can't stop mpv's built‑in native context menu from showing up.

In my input.conf I currently have:

MENU      script-binding dyn_menu/show
Shift+F10 script-binding dyn_menu/show

When I press Shift+F10, the first press opens the plugin's context menu, but pressing it again opens mpv's native context menu instead. The same thing happens with right‑click. The first click shows the plugin menu, the next click shows the built‑in menu. The exact same behaviour happens even if I comment out the MENU and Shift+F10 lines in input.conf.

How can I completely disable mpv's built‑in context menu so that only mpv-menu-plugin handles right‑click and Shift+F10?
