Wyze floodlight with Echo Show 8

One floodlight connected easily and shows on Alexa screen and I can talk from that screen. The older floodlight shows up in Alexa, but gives error message about the microphone needing to turned on and won’t work. Can’t turn on in Alexa. In Wyze I can turn it on from the app, but it turns off when I exit the app. How can I turn the speaker/microphone on all the time so Alexa will work with it?
