Probably best to use ELRS and not sbus. (Especially since I couldn’t find a single source how to even activate sbus on that receiver…)
Information about setting up ELRS can be found in the wiki here, or in the forum here, here, here or here.
TL;DR:
Try setting
SERIAL1_PROTOCOL = 23
RC_OPTIONS = 8224
RC_PROTOCOLS = 512
RSSI_TYPE = 3
