Assaulted by a DoorDash courier

Was running down I Street SW (a block from S Capitol) and a Door Dash biker punched me in the chest. Tried to avoid his clothesline, still hit me. First—what the fuck?! Second—I’ve called MetroPD (though I felt like I was wasting their time) and they asked if I wanted an ambulance. Assault was the word they used. Its a gnarly bruise. It was in front of an apartment w cameras, though I doubt anything will come of this other than me being shaken and worried about any e-bike in the sidewalk for the time being. Any additional steps I can take?
