How to flash Tasmota over ESPhome; but without the bulb showing in ESPhome on HassIO

Hi,

I have been messing around trying to get a Merkury A21 bulb working with ESPhome but unfortunately, due to the way things seem to be configured and the bulb hardware, I always have two lights showing in home assistant to control. One for the white and the other for the colour., From what I can read Tasmota covers the Merkury bulb pretty well over MQTT but I do not know how to flash Tasmota onto the bulb now that it has ESPhome installed. And on top of that, the bulb has disappeared from the ESPhome plugin in HassIO so I have nothing to fall back on. Please help!

Set up the web component in esphome,then upload via the web page.

Thank you @nickrout that worked perfectly.
