Can anyone help with Alexa in my 2021 Equinox... looking for solutions?

Choose this because it’s Thursday

I bought a 2021 Equinox in July, but I miss having Alexa which I used in my 2002 Honda Odyssey. I connected it with an aux cord and an Echo Auto. The Equinox doesn’t have an aux, so I Googled it and found out that the vehicle should have an app. I looked for apps on the screen, but there isn’t one. After some digging, I think I might need OnStar. So today, I signed up for OnStar, which took over an hour, but whatever, I thought I’d finally have Alexa. I signed up for the premium package; they do give me three months free, which is nice, but still no apps. I went to settings and downloaded updates, but it doesn’t need any. What else can I do? And when I say there are no Alexa apps in the apps section, I mean there are no apps at all to download.

Oh boy, get ready for a hard sell if you go to cancel OnStar.

Do they let you cancel online now? When I canceled a few years ago, it required calling and I got the hard sell to stay. XM used to be like that, but you can cancel XM online now.
