Make token appear/vanish with an effect?

I'd like to make various tokens appear or disappear with an FX effect, but I can't figure out how. Is there some macro command I can use to change a token's layer?

If you turn on “advanced keyboard shortcuts” in your settings tab, you can use a keyboard shortcut to change the layer for multiple tokens. This doesn’t produce an FX, but I hope it helped.

FX are a pro feature, unfortunately. With the API, you can use a macro that calls one script to send the token to the GM layer, and calls another to generate an FX command. If your game was created by an active Pro member, you have this capability. Without it, you pretty much need to do it manually.

I don't know if they're pro. I know they're a subscriber, as the game has several features that I've seen as limited to subscribers, but I'm not sure if they're the highest tier. Is there a way I can check? I do have access to the FX tool, but I don't know how to access the API. I can create macros, at least, is that all I need? Edit: I do have access to the API. I'll take some time to try to figure this out.
