Error: was not able to retrieve AAS token with the provided OAuth token

I follow https://github.com/EFForg/apkeep/blob/master/USAGE-google-play.md to obtain the oauth_token but the next step results in
Error: was not able to retrieve AAS token with the provided OAuth token. Please provide new OAuth token and try again.

I'm using a regular personal google account without any special settings. 2FA not activated. Retries in Chrome and Firefox with v0.17 and v0.16 of apkeep-x86_64-pc-windows-msvc.exe all result in the same error message.
The google account is not currently associated with an android device. Is such an association a prerequisite?

Resolved: the error was due to a syntax error in the https://github.com/EFForg/apkeep/blob/master/USAGE-google-play.md instruction line
apkeep -e '[email protected]' --oauth-token 'oauth2_4/...'

The solution is to not enclose the oath token value in single quotes. The correct syntax is
apkeep -e '[email protected]' --oauth-token oauth2_4/...

The google account is not required to be associated with an android device.

Please update the guide at https://github.com/EFForg/apkeep/blob/master/USAGE-google-play.md with the correct syntax.

Also add information about the AAS token. Does it automatically expire? After how long? Can it be manually revoked? How?
