Tips for Managing a Customer Advisory Board (CAB) Effectively

Looking for advice/best practices on CAB. My company has had a decently active CAB for the past year or so. It was previously owned by product marketing but we've had some turnover so right now CAB is on pause. I started in January as Lifecycle Marketing Manager and I'd really like to take over running it. BUT I'm afraid they're going to give it to someone more closely aligned to product. So my question is how do I make a pitch that I should own this and not someone from product? (or is it better if product retains control?) And related, we have a brand new CMO starting today so I'd like to prep some ideas I have for the CAB to show that I'm prepared and can bring a lot to the table - if anyone has any best practices or templates they'd be willing to share, I'd appreciate it!
