Execute on mob with NBT regardless of the NBT value (1.19.2)

Question

I'm trying to execute a command if a mob has the Owner NBT tag, regardless of who the owner is. How would I do this, if possible?

I'd like to be able to do something like /execute as @e[nbt={Owner=""}] or /execute as @e[nbt={Owner="*"}]. Which don't work, as expected, but I'm hoping there's a way that I didn't think of or simply don't know.

I intend to make something that only affects players and tamed mobs. It doesn't matter who tamed the mob, as long as it is tamed it should be affected.

Here is the command you probably want:

execute as @e if data entity @s Owner run <Command>

This will run if the if data is successful, it doesn't check for any specific value. For example, when I tested this only the entity with the Owner nbt, in my case an item, ran the command, and not the player. As I don't have the nbt on myself.
