Paste the user_login in the URL of a wordpress button

Question

https://app.website.com/?user_login?

After nearly 15 years of reading your solutions.

Today it's my turn to ask help. I have a wordpress website, website.com site and an application app.website.com with bootstrap, when a user registers is on my site I use his unique user_login to create a space for him. I would like to create a "Dashboard App" button on my menu so that when he logs in, he just has to click it to go to app.website.com/user_login. But I can't find the solution. Currently I just manage to show him the link in his wordpress account like this :

<p>
    <?php
    printf(
        '<strong>' . wp_kses( __( 'Otherwise, please login to your application here: <a href="https://app.website.com/%1$s/">app.website.com/%1$s/</a>', 'woocommerce' ), $allowed_html ) . '</strong>',
        esc_html( $current_user->user_login )
    );
    ?>
</p>

How can I put this link in a button in my menu?

Thank you in advance Best regard

This is a small plugin I made for you. Put this code in a php file and upload it as a plugin, and activate it. Then put the shortcode [my-awesome-button] in a post or page, and there it will appear the button. If the visitor is not logged-in, nothing will appear.

<?php

/*
Plugin Name: My Awesome Button
Description: The shortcode [my-awesome-button] will be replaced with the HTML code for a button for logged-in users and for guests it will be replaced with an empty string (so it will be removed). This will work for posts and pages.

add_filter( 'the_content', 'my_awesome_button_function', 99999999999 );

function my_awesome_button_function( $content ) {
    if ( strpos( $content, '[my-awesome-button]' ) !== false ) {
        if ( is_user_logged_in() ) {
            $current_user = wp_get_current_user();
            $button_html = '<a href="https://direktoriku.com/shopping/?user=' . esc_attr( $current_user->user_login ) . '"><button>Click me</button></a>';
            $content = str_replace( '[my-awesome-button]', $button_html, $content );
        } else {
            $content = str_replace( '[my-awesome-button]', '', $content );
        }
    }
    return $content;
}
