Inspired by a recent computation of holographic entanglement entropy in flat space holography, we proposed a covariant prescription to compute holographic entanglement entropy and Poincare blocks (Global BMS blocks) in the context of three-dimensional Einstein gravity in flat space. This prescription allows us to relate the kinematics of BMS field theories to bulk computations in an asymptotically flat space. I will first present a prescription based on worldline methods in the probe limit, inspired by analog calculations in AdS/CFT. Building on this construction, I will propose a full extrapolate dictionary and use it to compute holographic correlators and blocks away from the probe limit. I will conclude by commenting on relations between this work and other approaches in the literature.
