How to add Confirmation dialog in the custom link

[akshay225063]

Hello ,
@jeremystretch @danner26
I have created 2 custom links "Block company" and "Unblock company" .

Currently If I click on any of the button then it will do the required operation but I need to add a confirmation dialog before it will do any operation just like we have inbuilt confirmation dialog added for "delete" button.

Can anyone provide any suggestion it will be great help.
