Sensors for RF remote control (switch) automatically created in Home Asssistant?

I have a NodeMCU ESP8266 OpenMQTTGateway with STX and SRX so able to both receive and send RF signals. Version 1.5.1 (as 1.6.0 is only a few days old and I flashed it last weeek). Home Assistant 2023.5.4 on a Raspbery Pi 3B running Raspbian latest.

The gateway was automatically named OpenMQTTGateway_ESP8266_RF
The Home Assistant integration seems to work well as entities were automatically created such as GatewayRF, SYS: Connectivity, SYS: Free Memory, SYS: IP, SYS: RSSI, SYS: uptime. Other sensors that were automaticaly created are SYS: Auto Discovery, SYS: Erase Credentials, SYS: Firmware Update, SYS: Restart Gateway

When I push the ON button on the RF remote control I can see the GatewayRF sensor captures the reading 11111111 and the message is published as well:
home/OpenMQTTGateway_ESP8266_RF/433toMQTT {"value":11111111,"protocol":1,"length":24,"delay":309,"tre_state":"-","binary":"11...","raw":"9594,..."}

Same when I push the OFF button, GatewayRF captures the reading 22222222
home/OpenMQTTGateway_ESP8266_RF/433toMQTT {"value":22222222,"protocol":1,"length":24,"delay":309,"tre_state":"-","binary":"10...","raw":"4657,..."}

However, there is no switch sensor automatically created in Home Assistant. Should they be manually created?

When querying the mosquitto server about the topics created, these show in the list:

Client (null) received PUBLISH (d0, q0, r1, m0, 'homeassistant/device_automation/4JF8J48F7P3D--11111111-RF/config', ... (213 bytes))
Client (null) received PUBLISH (d0, q0, r1, m0, 'homeassistant/device_automation/4JF8J48F7P3D--22222222-RF/config', ... (213 bytes))

So it seems the topics are create but not the switch sensors for the RF remote control buttons?

I would expect
to be automatically created

It is my understanding that the sensor SYS: Auto Discovery should be switched on and the MQTT enable newly discovered devices should be switched on as well.

Guidance is much appreciated in advance.

Thank you!
