src/services/youtube/api.ts:90:37 - error TS2322: Type 'OAuth2Client' is not assignable to type 'string | GoogleAuth | OAuth2Client | BaseExternalAccountClient | undefined'.
  Type 'import("/home/l1media/youtube-synch/node_modules/google-auth-library/build/src/auth/oauth2client").OAuth2Client' is not assignable to type 'import("/home/l1media/youtube-synch/node_modules/googleapis-common/node_modules/google-auth-library/build/src/auth/oauth2client").OAuth2Client'.
    Types have separate declarations of a private property 'redirectUri'.

    24     auth?: GoogleAuth | OAuth2Client | BaseExternalAccountClient | string;
           ~~~~
    The expected type comes from property 'auth' which is declared here on type 'GlobalOptions'
