you can download KCS firmware for a test. just let esp32 board power on, then router power off, wait for a moment, router power on, then check esp32 whether is connected to router by ethernet.
Thank you. I would expect what you say to be the normal behaviour; nevertheless, it just doesn't do that with esphome.
It does, however, work with tasmota using this template. https://templates.blakadder.com/kincony_KC868-A2.html
Also, with esphome you can only use ethernet or wifi. With Tasmota both work without problem

How are all the pins from the module connected? I'm especially interested in where the RST pin is connected. Thank you.

RST pin connect to MCU's pin, but not MUST need to use it.

Which pin is the ESP connected to? In the video I saw that all the pins are connected to the board but I couldn't find any information on which ports the ESP is connected to. I need the RST pin to be able to reset the GSM module as it sometimes freezes.

our KCS firmware not used RST pin. if you write your own code want to RESET by ESP32 using your own code. you can let RST pin connect to any esp32's free gpio.

That's exactly what I'm asking. SIM800L is connected to a board with a fully installed pin header. From the schematic it's not entirely clear to me where the individual pins go to the esp32. How should I connect the RST pin to the esp32 when I have SIM800L connected to the pin header. If I understand correctly, pin headers C and B from the picture are used to connect the SIM800L.

B and C in image is SIM800L, you can check pin define on RED pcb, there are lable for pins.
on KC868-A2 PCB SIM800L socket pin define see this photo:

From this it is not entirely clear to me where the output (3)RST_GSM leads. On the board there is only a connection between (3)RST_GSM and (2)RST_GSM? I want to connect this PIN to some free ESP32 IO. Please advise where to make the connection. Thank you.

only GSM_TX and GSM_RX from ESP32's pin, it's free GPIO.

Sorry for the late reply.
I tried as you suggest but I receiv the follow error:
esptool: error: argument operation: invalid choice: 'merge_bin' (choose from 'load_ram', 'dump_mem', 'read_mem', 'write_mem', 'write_flash', 'run', 'image_info', 'make_image', 'elf2image', 'read_mac', 'chip_id', 'flash_id', 'read_flash_status', 'write_flash_status', 'read_flash', 'verify_flash', 'erase_flash', 'erase_region', 'version')
