I am new to write gmail add-ons. Generally Add-ons are shown only when we open 1 thread. My question is: Is there any way to show the add-on on selecting a mail from inbox or any other label, without opening the message thread?
A gmail add-on cannot be triggered when a selection is made through checkbox. But it is a good thought, really. For some reasons , triggering is only possible when you open a thread. However it can also trigger when you switch between messages.
