How to place custom macro icon just below insert link macro

Hi Team,

I tried to put my custom macro icon within Confluence page editor “Insert more content” toolbar. I’ve followed below mentioned document , custom macro starts appearing after “Symbol macro” .

I want to place my custom macro just below “Link” macro . Could you please suggest what value of weight do i need to pass to place it ? I’ve also tried with -ve weight value and different combination of weight value but not able to change its position above symbol macro.
