How to use postMessage to receive and send some information from Appian page to Angular page

Hello All,

We have an Angular page where we are displaying Appian task list.  We have provided a run button in one of the HTML table's column , which simply run Appian task in a new window/tab.

I would like to know if there is a way to send some message back to Angular page after user complete the task/ or click submit button.

I would like to get the updated task list automatically (refresh the task list section) once user finish any Appian task.

Please share your thoughts.

Thanks,

Gaurav
