I need to maximize the Omni channel window on click of a custom button saying they are online. I don't want to pop up a window in seperate browser, but instead I want to maximize when they click that button. I found many for Live agent related, but I didn't found any methods relevant to Omni channel. Any help would be greatly appreciated. 

Figure 1: This is initally my Omni Channel window before click of a button.
Figure 2: I want the Omni channel  like this to pop up after clicking of a button. Not, in seperate window.









 

I am not getting milestone tracker at case level in service console.

I have valid criteria for Milestones in active Entitlement process( Case Status equals New), Gave permission to Entitlement object at profile level,
gave field level security "Visible" to Entitlement Name field and also added it to case feed page layout. Gone each and every documentation and repeated whole steps, but not able to success in this. Any help on this would be really helpful. Thanks in advance.
