The snap version of neomutt expects configuration files in

 ~/snap/neomutt/current

The main configuration file, for example, has to be placed in

 ~/snap/neomutt/current/.neomuttrc

Note that this directory is versioned and is backed up when the snap is removed (see https://snapcraft.io/docs/data-locations#heading--user).

OAuth2 Support

Follow the direction in https://neomutt.org/guide/optionalfeatures#6-%C2%A0oauthbearer-and-xoauth2-support or simply run

 neomutt.oauth2 --help

to get instructions on how to create Client ID and Client Secrets. Create a refresh token,

 neomutt.oauth2 --generate_oauth2_token

And add the following to the Neomutt configuration file,

 set imap_authenticators="oauthbearer"
 set imap_oauth_refresh_command="oauth2 --quiet \
   --user=[email_address] \
   --client_id=[client_id] \
   --client_secret=[client_secret] \
   --refresh_token=[refresh_token

Note that within the Neomutt configuration file, the oauth2 script can be called without specifying a path.
