The phrase "Open Supported Links" is primarily an Android system setting that controls which app handles specific web links, so for Google Chrome, this is generally about ensuring it is set as your default browser and that the operating system allows it to open web links directly. On Android, to manage this, you should go to your phone's Settings, then find Apps (or Apps & Notifications), select Chrome from the list, tap on Set as default (or Open by default), and confirm that the Open supported links toggle is enabled, which allows Chrome to open the web addresses it's configured for. On an iPhone or iPad running iOS 14 or newer, you simply need to make Chrome your default browser by going to the main device Settings, scrolling to the Chrome app, tapping Default Browser App, and selecting Chrome, which will ensure all external web links open directly in Chrome instead of Safari.
