How do you turn off google assistant so you can use a selfie stick?

In Android phone I figured out how to turn off google assistant since it kept coming on every blasted time I tried to plug selfie stick in to the headphone jack, but now that it is off a stupid popup thing keeps coming up asking me if I want to turn google assistant on? Is there some way to bypass this silliness and just make the selfie stick thing work the way it is supposed to work (you click a little button on the stick and it is supposed to send a signal via earphone jack to camera app to snap a shot. Before Google installed this blasted piece of software on it it all worked right, now that thing intercepts and makes it not work)

say "siri fix this pos"
