Access token not getting refreshed automatically

According to Google node sdk docs: “This library will automatically use a refresh token to obtain a new access token if it is about to expire.”. But it’s not happening in my case. After an hour or so I’m getting 400 invalid_request error.

Here’s my implementation:

import { calendar_v3, google } from "googleapis";

const oauth2Client = new google.auth.OAuth2(
      process.env.NEXT_PUBLIC_GOOGLE_CLIENT_ID,
      process.env.GOOGLE_CLIENT_SECRET,
      process.env.NEXT_PUBLIC_GOOGLE_REDIRECT_URI
    );
    oauth2Client.setCredentials({
      refresh_token: gRefToken,
      access_token: gAccToken,
    });

const calendar = google.calendar({
      version: "v3",
      auth: oauth2Client,
    });

resCalEventsFromLastSync = await calendar.events.list({
        calendarId: "primary",
        timeMin: new Date().toISOString(),
        timeMax,
        singleEvents: true,
      });

PS: My app is currently in unverified state but note sure if that has something to do with it.
