from what i know, it just exits when input is given i want to press esc to call a method and be able to type anything in Console.ReadLine() at the same time

Maybe Console.KeyAvailable() running in a task? Something like 
using System;
using System.Threading;
using System.Threading.Tasks;

var keyListenerTask = ListenForEscape();

await DoYourMainWork(_cts.Token);

await keyListenerTask;

async Task ListenForEscape()
{
    if (Console.KeyAvailable)
    {
        var key = Console.ReadKey();
                
        if (key.Key == ConsoleKey.Escape)
        {
            // do your thing
        }
    }

    await Task.Delay(50);
}

async Task MainWork()
{
    for (int i = 0; i < 100; i++)
    {
        Console.WriteLine($"Working... {i}");
        await Task.Delay(1000, cancellationToken);
    }
}
using System;
using System.Threading;
using System.Threading.Tasks;

var keyListenerTask = ListenForEscape();

await DoYourMainWork(_cts.Token);

await keyListenerTask;

async Task ListenForEscape()
{
    if (Console.KeyAvailable)
    {
        var key = Console.ReadKey();
                
        if (key.Key == ConsoleKey.Escape)
        {
            // do your thing
        }
    }

    await Task.Delay(50);
}

async Task MainWork()
{
    for (int i = 0; i < 100; i++)
    {
        Console.WriteLine($"Working... {i}");
        await Task.Delay(1000, cancellationToken);
    }
}
Basically, every 50ms check if a key has been pressed, and if so, do something
