The interaction package comes complete with a set of familiar avatar prefabs that be used in any project. Including XR and non-XR avatar options. You should find that these are already populated in your Avatar Settings. These prefabs can be found in
Packages > Immerse Interaction > Runtime > Avatar > Avatar Prefab
It is typically easier to create a new avatar by creating a Prefab Variant of the included example and modifying it to your specifications.
If you would prefer to start fresh, a utility has been included to create the basic structure of an Avatar with the required components in order to take advantage of all the SDK's features. This can be found in
GameObject > Create Other > Immerse > Interaction > Create Avatar
