Need a little help finishing custom genie vessel macros/effects. [DND5E]

I have a "Genie's Vessel" feature setup as an action for a character. The goal is to do the following:

1. Consume the 1/LR resource (done)
2. Use TokenFlip to change them into their vessel (done)
3. Disable an active Passive Effect: their lantern
4. Teleport the player to a new scene: vessel interior

Could someone please teach me how to add the final two events to my action?

I believe I can just use MATT to give them a button to undo everything from within their vessel, but if that whole vessel scene change doesn't seem realistic, I would like to replace #4 with adding the blind condition and then somehow make the whole action toggleable so they can reverse everything.

Thank you.
