Add external link desktop on android --> forces login?!

Nextcloud version 15.0.5

I want to create a shortcut on an android device directly to a external link of my nextcloud. So I open the link in Google Chrome browser and click on “add to desktop” and a new desktop icon appears (like a new app).

When I click on this shortcut I will be forced to login to nextcloud. That’s a problem because the link is an external link so I shouldn’t be forced to login.

Can anybody help?
