I repply to myself.

After a lot of reading and trying, I finally managed to add the Google Drive videos to the collection. I'm sharing in case anyone is interested. Indeed, the Google Chromecast (I don't know about other Android TV devices) has some restriction on saving files to external storage, which is why it did not output the .strm files. The solution is to use the internal storage, but Kodi does not show you the internal routes by default. You must first find out the route and add it with a source. There I leave a guide in case someone looks for it one day https://aguacatec.es/anadir-videos-de-go...n-de-kodi/

Thanks!
