AsyncMQTTClient does not work for SSL enabled brokers

The UI doesn't accept port 8883 and 8884 for MQTT as AsyncMQTTClient does not support SSL connections.

To my knowledge AsyncTCP on ESP32 does not yet have SSL support:

Last time I looked at this it appeared that SSL requires too much RAM be be feasible on the esp8266 with all of the other stuff the framework holds in memory - it needs about 20k of RAM just to to the handshake.

Why not just use https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/protocols/mqtt.html
