After successfully installing the Chrome extension, you’ll notice a Dex icon next to Twitter user profiles when browsing Twitter on the web. Clicking this button will automatically add the selected profile to Dex or link it to an existing Twitter contact:

If the Dex button does not pop up immediately, try refreshing the page—this will usually allow the overlay to pop back up on the screen!
Once you’re able to access the in-app Dex integration, you’ll be able to add details such as birthdays, notes, calendar events, and more right within the Twitter webpage! Click “Open in Dex” to navigate away from Twitter and into Dex if you’re looking to access in-depth information about reminders, events, and contact details!
