XAMPP (Apache) and Nextcloud help to set

Hello, I would like to be able to find definitive help. I have the XAMPP program installed on Windows to use the Apache server with my domains. The problem I have is that I have not been able to configure Nextcloud AIO because it uses the same ports as Apache. I have tried to follow the reverse proxy instructions but I don’t think I understand them very well, which is why I have not been able to install it. Is there any video or help you can give me to achieve this? My knowledge is very basic.
