Excel Add-in "Data Streamer" with ESP32


I would like to connect an ESP32 via the Data Streamer to Excel.
Unfortunately Excel dont show any Data although the correct Port and the correct baud rate are selected.
It works great with an Arduino MEGA, but I would like to use an ESP32.
Does anyone have the same problem and a solution to it?
Or is a connection between the ESP32 and Excel via the data streamer not possible at all?
