get_the_date

Dear,

i am trying to get the date in my wp bakery grid builder.

so far i have created a shortcode which functions but it echos back te page date.

<?php

   function dotavatiar_function( $format = '', $post = null ) {
    $post = get_post( $post );
 
    if ( ! $post ) {
        return false;
    }
 
    $_format = ! empty( $format ) ? $format : get_option( 'date_format' );
 
    $the_date = get_post_time( $_format, false, $post, true );
 
    /**
     * Filters the date a post was published.
     *
     * @since 3.0.0
     *
     * @param string      $the_date The formatted date.
     * @param string      $format   PHP date format.
     * @param int|WP_Post $post     The post object or ID.
     */
    return apply_filters( 'get_the_date', $the_date, $format, $post );
};
add_shortcode('dotiavatar', 'dotavatiar_function');

I want to get the posts-date. This function i have written above as i said echos the page date not the posts.

Thank you
