MQTT and Tasmota

Dear all,
unfortunately a newbie question.
I started MQTT and extended the Tasmota flashed gosund plug.
Within the File Explorer I saw the switch status but I am not available to see them as an entity in HA :-(.
What I’m doing wrong?

What I meant is in the MQTT Explorer view I saw the changes


You will need to add the tasmota device via integration

And all these things…
