Thanks to all who answered all of my questions.
I am not a builder, don’t have a bunch of tools so trying to build a frame was going to be a challenge. In all of my research I found a medicine cabinet build at
https://docs.smart-mirror.io/docs/hardware.html I didn’t buy the monitor he suggested and went with a 24 inch monitor I found on Craigslist. After stripping it down to bare bones, I placed on top of the mirror and of course it was about 1/4 inch too big. Ugh. Gambled and bought a 23 inch monitor and after stripping it down it was perfect

Removing the mirror from medicine cabinet was not as easy as described. I had to pry the wood apart on 3 sides and after putting the new mirror in, I used wood glue and large clamps to rebuild.
I called a bunch of local glass companies and found one who would sell me a 13x26 one way mirror for $75. That was less than the cost of an acrylic one from the vendor many use. Call around for sure. This was my 7th call. Most other places wanted $125 or more.
I am not hanging it on a wall, but resting on top of my mantle. I added a few eye hooks and 100 pound picture wire. I added a few 100 pound picture frame holders into the wall and put the wire over the hooks to prevent any chance of it tipping over.
To control the screen I am using an Alexa enabled smart plug. I have an Echo in my living room so I didn’t build Alexa into the mirror. I choose the smart plug for a few reasons. It allowed me to add it to my morning and evening rituals so it turns on and off at certain times. I also added an applet from IFTTT that is based on location. It turns on or off automatically when I leave or enter my subdivision.

Here is what it looks like mounted on the mirror. I used tarp straps to keep everything tight.
