how to reorder Itmedia menu in profile menu

Hello,

I read a lot upon how to reorder BP profile menu, I tried, but I am failed to reorder the RTmedia menu item, the following is what I searched:

https://rtmedia.io/docs/developers/reordering-media-tab-buddypress/

add_filter('rtmedia_media_tab_position', 'reorder_rtmedia_media_tab_position', 10, 1);
function reorder_rtmedia_media_tab_position( $pos ){
    return 1;
}

I want to put Rtmedia menu item at second position, and I changed the above 10 to 20, and add 

$bp->bp_nav[‘media’][‘position’] = 20;

the following is the full code what I am using, but I failed:

<?php

/**

* @package WordPress

* @subpackage Kleo

* @author SeventhQueen <themesupport@seventhqueen.com>

* @since Kleo 1.0

*/

/**

* Kleo Child Theme Functions

* Add custom code below

*/

function my_change_profile_tab_order() {

global $bp;

$bp->bp_nav[‘activity’][‘position’] = 10;

$bp->bp_nav[‘media’][‘position’] = 20;

$bp->bp_nav[‘mycred-history’][‘position’] = 30;

$bp->bp_nav[‘forums’][‘position’] = 40;

$bp->bp_nav[‘friends’][‘position’] = 60;

$bp->bp_nav[‘groups’][‘position’] = 70;

$bp->bp_nav[‘blogs’][‘position’] = 80;

$bp->bp_nav[‘messages’][‘position’] = 90;

$bp->bp_nav[‘notifications’][‘position’] = 100;

$bp->bp_nav[‘profile’][‘position’] = 110;

$bp->bp_nav[‘settings’][‘position’] = 120;

}

add_action( ‘bp_setup_nav’, ‘my_change_profile_tab_order’, 999 );

add_filter(‘rtmedia_media_tab_position’, ‘reorder_rtmedia_media_tab_position’, 20, 1);

function reorder_rtmedia_media_tab_position( $pos ){

return 1;

}

Would you please show a right way to reorder it?

Thanks.

Alex
