making custom router

[artimesphoenix]

I want to make a custom Laravel router.
It will route based on post input values (and user current stage defined in cache) instead of uri.
This will be useful for creating a telegram bot.
If you know the right steps to create a laravel router or what files I need to rewrite, I'd appreciate it if you could share it.
This code is an example of my concept :

<?php
TelegramRoute::stage('default')->text('change profile picture', function () {
    Telegram::User()->setStage('upload-profile-picture');
    Telegram::sendMessage('Please upload your image');
});
TelegramRoute::stage('upload-profile-picture')->group(function () {
    TelegramRoute::text('exit', function () {
        Telegram::User()->setStage('default');
    });
    TelegramRoute::image(function ($image) {
        $image->save(storage_path('profiles'));
        Telegram::sendMessage('Your profile changed successfully');
    });
});
