Can you set Thunderbird keyboard shortcut to toggle the Calendar Pane?

Using Thunderbird 128.5.2esr and the tbkeys-lite 2.3.0 add-on, I’m unable to figure out how to open the Calendar Pane set to the Calendar List window (where the mini-month is also shown). This is a window that flys out from the left. I would like it to be controllable just like how F11 toggles the Events pane.

This window is normally accessible via the File Menu from View / Calendar / Calendar Pane / Show Calendar Pane. Pressing something like F3 would be most welcome to toggle this pane on and off.

Do you know a way to accomplish this?

Watching the command via the Error console shows TogglePaneSplitter(‘calsidebar’) firing. But I’m unsure of how to map this to F3.
