But... there's more.
Of course, Google Home being what it is, you ought to be able to send feedback via voice, oughtn't you? The answer is yes. You should be able to... and you can! Simply say the following:
Ok, Google [or, Hey, Google]
then
Send Feedback.
And now you can fire away your bug or feedback report by voice.
