The RXD0 pin is used as one of the touch inputs, so you can’t use the serial port for flashing (unless you cut a track). However tuya-convert works fine to flash it. After Tasmota is installed, a relay will click once per second as this in the default location for the status LED. You just need to connect quickly to the AP, and browse to, and configure it as a generic module to stop the clicking. You can then go through the normal process, and restore this template.

Some numbers I found internally (taking off the cover) are 120K3S_WIFI_SV5 (for searching). I have uploaded a bunch of images here: https://github.com/sillyfrog/contact/issues/3

Finally, as there are a number of LED’s, the new v9.1+ template correctly configures LedLink.
