Esp32 webportal development or implementation.

This project is for experienced and knowledgeable of Esp32 and Webportal person.

Need to add a webportal to an Esp32.
Currently I have a project that runs in AP mode only.
It serves a webpage that’s is in the SPIFF.
Typically you connect to Esp32 WiFi network from your device, enter set WiFi credentials and once connected user has to input the IP address 192.168.4.1 on their browser and then the webpage is displayed.

I would like to implement something like the WiFimanager or AutoConnect library.
Where the user can connect to the esp32 WiFi , once connected the portal is displayed,
Have options to setup and save WiFi credentials to join near WiFi networks.
MQTT options as well.
If no WiFi credentials or network or MQTT is available keep running in AP mode and be able to display the mentioned webpage.
Also be able to delete save credentials via portal and push button.

I will provide a zip with the sketch ( arduino IDE) and html files. The data is loaded to the spiff using esp32 upload tool.
