Advertising gambling apps in my game?

I've been approached by a gambling app developer, who wish to "sponsor" my game (have my add images for their game in mine).

This is in the UK where real money gambling apps are legal, and advertising of them is legal.

My game is not an 18+ only game, although again, from a legal perspective I don't think this is against the law.

What I'm not sure about is, does Apple allow this? Although there is plenty of info in Apple's Ts & Cs about how to submit gambling apps for review, there's nothing I can find about allowing gambling ads in a non-gambling game.

Guidelines indicate:

3.1.7 Advertising: Display advertising should be limited to your main app binary, and should not be included in extensions, App Clips, widgets, notifications, keyboards, watchOS apps, etc. Ads displayed in an app must be appropriate for the app’s age rating, allow the user to see all information used to target them for that ad (without requiring the user to leave the app), and may not engage in targeted or behavioral advertising based on sensitive user data such as health/medical data (e.g. from the HealthKit APIs), school and classroom data (e.g. from ClassKit), or from kids (e.g. from apps in the Kids Category), etc. Interstitial ads or ads that interrupt or block the user experience must clearly indicate that they are an ad, must not manipulate or trick users into tapping into them, and must provide easily accessible and visible close/skip buttons large enough for people to easily dismiss the ad.

So, as your game is not an 18+ only game, you need to check thet the advertised app does not require 18+
