Command from mob detected via saddle

[umbral remnant]

I'm just working on this new mechanic tho anyway, If a player rides to a vehicle and go to it's inventory like in horse if you put a saddle on it and the command will be activated, if you remove it the another command will activated.

Is this possible or not and here's the code

GetEquipment doesn't work on entities so try using commands
