Those are two very different things.
It also may be a group that goes a pretty steady 23 mph, or it may be a group that has constant surges and attacks.
And there may be hills, and if there are hills, it may be a group that waits for everyone at the top, or at least does a rolling regroup, or it may be a group that eats its young.
The fitness and skill required will vary greatly depending on where this ride fits into the above referenced continuim.
As said above only one way to find out.
True. And OP...you could also do a trial run. You don't have to just dive into the deep end.
Rent an electric moped and pace the group you intend to ride with. If possible track speed with a Garmin and download it and then study the speed signature and elevation changes. Then compare that to your power production adjusting for the aero benefit of pacelining.
This will give you a better sense.
