1. A method of wireless communication at a first sidelink device, comprising:
transmitting, in response to an occurrence of an aperiodic trigger for a sidelink discovery probing message, the sidelink discovery probing message, the aperiodic trigger being based on a beam refinement procedure, the sidelink discovery probing message comprising at least a first identifier of the first sidelink device via multiple beams comprising a first beam;
monitoring for a probing response from a second sidelink device;
receiving the probing response on the first beam, the probing response comprising beam information for at least one beam of the multiple beams;
determining the beam information based on a mapping between a first resource for the sidelink discovery probing message and a second resource for the probing response; and
transmitting a sidelink discovery message on the at least one beam associated with the beam information.
