When using the hotkey, the spyglass does not render on the serverside, other players do not see me holding a spyglass!

In my case, others CAN see me holding the spyglass, but they don't see me using it (without a 3D model, as if I was just holding it in my hand).

To do this, when using the item, need to add a delay, apparently so that the server has time to read.
