Gravity-matter systems with non-abelian gauge symmetry can be constructed using the language of exceptional geometry and exceptional field theory.
I will first review some general aspects of this construction and then focus on the case of two-dimensional gravity where one can construct generalizations of Jackiw-Teitelboim gravity, in particular theories that are expected to be dual holographically to the M-theory matrix model.
