AP+STA with static IP & WEB inretface

[BARS2022]

Hi.
I want to connect ESP32 to Wi-Fi network (STA MODE). And I don't have any LCD, keyboard, etc in my device. Therefore I need set SSID and password with WEB UI (AT MODE). Also I need static IP for WEB UI and dynamic IP for Wi-Fi network. I want to make the next algorithm:
1) Enabling AP mode by long pressing the button;
1) Connect to ESP32 AP;
2) Go to ESP32 IP:Port TCP Server (Static IP) WEB UI;
3) Set SSID from list and write password;
4) Click "Connect" button;
5) ESP32 try to connect to Wi-Fi network;
6) If OK, run TCP Server with dynamic IP and disabling AP MODE;

I configuring TCP Server with WEB UI and I get http page with Wi-Fi network settings. But I don't now how change DHCP settings for dynamic IP after connect to network. How can I do this?
