GM’s official Bolt EV videos lists 21 separate videos on the Bolt, its features, and how to use it. The most recent is October 2020 titled Chevrolet EV Power Panel on charging, charging networks, including the roll out of the GM-EVgo expansion.
For experienced YouTube denizens the videos will appear stilted and awkward, but consider that the source is a stodgy legacy manufacturer. As such, you’re going to get the official GM line and nothing more. Even so, these videos can be useful, particularly to newbies and neophytes to the Bolt EV and to EVs in general.
