Edit Next/Prev file according to CPT

Hello,

I want to show the other posts on CPT in the Next/Prev section of my custom singular page. not show any taxonomies (Tag, Category, custom Tag, custom Category)
In this regard, I call the Next/Prev.php file for CPT layout and change in codes in accordance with the following method:
But not work ??

// Only display for CPT
if ( 'cpt' != get_post_type() ) {
	return;
}

// Term
$post_type = get_post_type( 'cpt' );
$post_type = $post_type ? $post_type : 'cpt';

// Args
$args = array(
	'prev_text'             => '<span class="title"><i class="fas fa-long-arrow-alt-left"></i>'. esc_html__( 'Previous Post', 'oceanwp' ) .'</span><span class="post-title">%title</span>',
    'next_text'             => '<span class="title"><i class="fas fa-long-arrow-alt-right"></i>'. esc_html__( 'Next Post', 'oceanwp' ) .'</span><span class="post-title">%title</span>',
    'in_same_term'          => true,
    'taxonomy'              => $post_type,
    'screen_reader_text'    => esc_html__( 'Continue Reading', 'oceanwp' ),
);

Thanks in advance
