There’s no documentation on UPROPERTY meta tags ToolTip and AnimNotifyBoneName.
Here are 2 pages from the documentation that list UPROPERTY specifiers and list their meta tags. But are missing ToolTip and AnimNotifyBoneName.
Properties page: https://docs.unrealengine.com/en-US/…ies/index.html

I only know they exist because they’re fairly common in the engine code. For example. Here is an example of those tags being used on Engine\Plugins\FX\Niagara\Source\NiagaraAnimNotifies\Public\AnimNotifyState_TimedNiagaraEffect.h
// The socket within our mesh component to attach to when we spawn the Niagara component
UPROPERTY(EditAnywhere, Category = NiagaraSystem, meta = (ToolTip = "The socket or bone to attach the system to", AnimNotifyBoneName = "true"))
FName SocketName;
