Support for chip from espressif family with Zephyr

Is it possible to use this module on an ESP chip (I'm trying to use it on ESP32)?
I'm able to build 'micro_ros_zephyr_module' using 'west build -b disco_l475_iot1' but I'm having errors caused by 'app.overlay' content when building with 'west build -p auto -b esp32_devkitc_wroom':

I found in this issue statement that this module should be usable on any board supported by Zephyr.

Thanks in advance.

Beginne mit app.overlay und dem west build-Befehl für esp32_devkitc_wroom; der gemeldete Fehler ist die nicht definierte usbotg_fs-Knotenbezeichnung während der Devicetree-Generierung. Vergleiche dies mit dem disco_l475_iot1-Build und ermittle, welche boardspezifischen Änderungen für die ESP-Unterstützung erforderlich sind. Als erledigt gilt die Aufgabe, wenn das Modul für das ESP32-Board ohne den Devicetree-Fehler erfolgreich gebaut wird.
