Help. Mirror glass fell off while driving

Luckily I saw it wobbling like a loose tooth and grabbed it before it flew away. Any advice on getting this reattached? I have defrost mirrors with blindspot monitoring so I want to get the glass back on right. I could have this handled under third party warranty but my deductible is $100 which is more than food glue.
