1. A method of wireless communication performed by a remote user equipment (UE), comprising:
transmitting, to a relay UE, a request for a Layer 2 relay service and a relay service code associated with the Layer 2 relay service, the relay service code identifying a relay type of the Layer 2 relay service;
receiving, from the relay UE, a message indicating whether the relay UE accepts the Layer 2 relay service associated with the relay service code,
wherein the message indicates that the relay UE accepts the Layer 2 relay service when the relay service code indicates that the Layer 2 relay service is associated with an emergency service, and
wherein the message indicates that the relay UE rejects the Layer 2 relay service when the relay service code indicates that the Layer 2 relay service comprises a type of Layer 2 relay service that is not associated with the emergency service;
establishing, based at least in part on the message indicating that the relay UE accepts the Layer 2 relay service associated with the relay service code, a radio access signaling radio bearer (SRB) for the Layer 2 relay service using a remote UE radio access SRB configuration,
wherein the radio access SRB for the Layer 2 relay service is established based at least in part on the relay UE providing, to a base station, an indication that the relay UE supports the Layer 2 relay service and receiving a relaying configuration from the base station based at least in part on the indication; and
