ESP32 Notifications

[FLBESSE]

Hello, I would like to make a wifi access point with an esp32.
This access point would be without password. But I would like the user to identify himself on a web page to connect to the network. So I'm looking to create a notification on the user's phone so that he goes to the web page as is the case on public networks.
I searched a lot, I don't know how to do it.
Do you know if this is possible and if so how?

You're looking for 'captive portal'. They exist for ESP32 chips; they're usually used to allow someone to connect the ESP32 to an existing access point from their phone. (E.g. esp-wifi-manager)
