WifiManager error with Arduino UNO R4 WiFi

Hello, I have tried the basic code for the ibrary WiFI Manager, but I get the error: Compilation error: 'WiFiManager' was not declared in this scope

It's the basic code so it should work, here is the code

#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager


void setup() {
    // WiFi.mode(WIFI_STA); // explicitly set mode, esp defaults to STA+AP
    // it is a good practice to make sure your code sets wifi mode how you want it.

    // put your setup code here, to run once:
    Serial.begin(115200);
    
    //WiFiManager, Local intialization. Once its business is done, there is no need to keep it around
    WiFiManager wm;


    // reset settings - wipe stored credentials for testing
    // these are stored by the esp library
    // wm.resetSettings();

    // Automatically connect using saved credentials,
    // if connection fails, it starts an access point with the specified name ( "AutoConnectAP"),
    // if empty will auto generate SSID, if password is blank it will be anonymous AP (wm.autoConnect())
    // then goes into a blocking loop awaiting configuration and will return success result

    bool res;
    // res = wm.autoConnect(); // auto generated AP name from chipid
     res = wm.autoConnect("AutoConnectAP"); // anonymous ap
    //res = wm.autoConnect("AutoConnectAP","password"); // password protected ap

    if(!res) {
        Serial.println("Failed to connect");
        // ESP.restart();
    } 
    else {
        //if you get here you have connected to the WiFi    
        Serial.println("connected...yeey :)");
    }

}

void loop() {
    // put your main code here, to run repeatedly:   
}

Uno R4 WiFi is not supported by that library

Do you know if there's any similar library that can be used instead of this one so I can request the wifi credentials? Thanks

I think the Arduino IoT Cloud supports WiFi provisioning
