Toyota RAV4 Moon Roof Install

Hi all! Prior to picking up my RAV4 this week, I am having a moonroof installed. Since the base model RAV4 doesn’t come from the factory with a moonroof, one will be installed. They don’t do it at the dealership but at a 3rd party. How do I know (or what can I ask for) that will ensure that the moon roof installed is a toyota factory/branded/warrantied moon roof? Do they have some sort of invoice for things like this? Just nervous about getting a second rate lookalike put in (it’s happened to me before with headlight covers. After 3 months they turned yellow).

Thank you all for any advice!!!
