How to use access token from google calendar in js

I have question regarding google calendar, and hope you can help me.

I have access_token from google calendar and that access_token was stored in localStorage.

          const googleAccessToken = e.vc.access_token;
          localStorage.setItem('googleAccessToken', googleAccessToken);

Now please help me understand how can I use this to avoid authorization every time.

For example I want to delete all events, And for that I wrote this code, and this code every time wants from me authorization:

   const handleDisconnect = () => {
    gapi.load('client:auth2', () => {
      console.log('loaded client');

      gapi.client.init({
        apiKey: API_KEY,
        clientId: CLIENT_ID,
        discoveryDocs: DISCOVERY_DOCS,
        scope: SCOPES_CLEAR,
      });
      gapi.client.load('calendar', 'v3', () => {
        console.log('sdsd');
      });
      gapi.auth2
        .getAuthInstance()
        .signIn()
        .then(() => {
          var events = bb;
          var makeRequest = resource => {
            console.log(resource);

            var request = gapi.client.calendar.calendars.clear({
              calendarId: 'primary',
            });

            request.execute(resp => {
              console.log(resp);
            });
          };

          for (var j = 0; j < events.length; j++) {
            makeRequest(events[j]);
          }
        });
    });
    };

Please help me to fixed that code with access_token for avoiding authorization
