Version

Please specify what version of the library you are using: [ "@pnp/spfx-controls-react": "^3.20.0"]

Expected / Desired Behavior / Question

As security group names can change, I think it makes sense to be able to select group by ID, instead of by its name. For groups it's even more relevant, as they don't have email property as users do.

It may either be able to check between both name/id or have a separate field for it.

Observed Behavior

defaultSelectedUsers only receives security group name.

Initially, security group support was added in #958, however, only for a name selection, not id.
