# Launch the addon

### Launch SyncThemCalendars

From now on, you can launch our addon, from Gmail, Google Calendars or Google Sheets, by clicking on the right side bar icon as show below : 

<figure><img src="/files/xfam7WF9udUWJMAVa0iq" alt=""><figcaption><p>Click on SyncThemCalendars icon directly in Gmail or Google Calendars</p></figcaption></figure>

The addon will open, and you can now create your first sync.

{% hint style="warning" %}
If after the installation, SyncThemCalendars icon doesn't appear in the side bar, you may need to refresh the page.

If after refreshing the page, the  icon still doesn't appear, are you using multiple Google accounts under the same Chrome Profile ?

&#x20;There is a limitation in Google Chrome, the simplest way to avoid it is to use the same Google account for the installation than the one you are logged in Google Chrome
