Accessing Nintendo Smartphone App notifications from PC browsers?

[HNKii]

I recently attempted to extract the URL of Nintendo app notification lists.
Miitomo was easy. Just go offline after entering the game, then click the notification. The in-app browser will throw a connection error warning, with the link displayed.
https://support.miitomo.com/en-US/public_announcements would be the link
Fire Emblem Heroes is a bit trickier. The offline method only creates a split second of connection error after it changes into "803-1000 Cannot use offline", but I still managed to record the process with a camera, and found out the link to be:
https://support.fire-emblem-heroes.com/en-US/public_announcements
Super Mario Run throws out it's App errorcode before the in-app browser even has a chance for displaying errors, but judging from the above examples, the link should be:
https://support.supermariorun.com/en-US/public_announcements
However, only the Miitomo one can be visited with a normal browser. The other two will just show a "Page cannot be read." error.
Anyone knows how to change the user agent so accessing these links work?

Try to spoof as Android and see if changes anything.
