For the beginner rides, probably not. A good hybrid would be fine provided it has tyres suited to road riding, but if the bike has suspension it’s not appropriate for group road riding and it’s unlikely you’d be allowed to participate. A lot of beginners start with a hybrid, become hooked on cycling and then buy a road bike.
For the main club rides, whilst it’s possible to use a hybrid you’ll likely find it more comfortable and efficient perched atop a road bike.
