QUESTION: Notifications file? Image? Or…?
First of all, I love this plugin! Thanks for making it. 

I’m just now discovering the notifications option. But I’m not sure what type of file it takes. I tried to use a png file hoping I could see a nice icon instead of their generic speech bubble, but it really did not like that. Haha

is there a way to use your own icon/image? If not, what does the file option take?

thanks!
