Yep, works perfectly 🙂

Maybe better like this :

add_action( 'bbp_template_before_single_forum' , 'xxxx_bbp_display_forum_description' );

function xxxx_bbp_display_forum_description() {

    $display_forum_description = bbp_get_forum_content();

    if ( bbp_is_single_forum() && ! empty( $display_forum_description ) ) {
    
        echo '<div class="bbp-display-forum-description">';
        echo $display_forum_description;
        echo '</div>';

    }

}

I found this solution :

add_action( 'bbp_template_before_single_forum' , 'xxxx_bbp_display_forum_description' );

function xxxx_bbp_display_forum_description() {
    echo '<div>';
    bbp_forum_content();
    echo '</div>';
}
