When viewing web-based experiences in the Quest, there are two ways to go.
The first option is the built-in web browser created by Oculus. This can be entered via the home menu in the app browsers
The second option is Google Chrome, which sometimes has to be installed outside the Quest.
When accessing a designated link, it is important to include "https://". If this is not at the beginning of the link, you will be unable to enter the VR mode.
