MQTT not showing exposed entity (brightness) for YSRSAI YSR-MINI-01 led controller

Hi, i have an YSR-MINI-01 RGB controller which is showing state, brightness, color_temp, color_xy, effect, and linkquality in Zigbee2MQTT Edge, but only color_xy and color_temp in HA. You can manually adjust brightness on the HA (there is a slider), but not via automation. Any way in manually push the attributes to HA?
