Can I use multiple tabs with an installed app?

[User.1.000.000.000]

I just noticed this post (see below) with @Saoiray

This might be why the tabs aren’t working… maybe it only works with the native “laptop button to add PWAs” rather than the work-around ones you recently learned about… see if you get a different result creating it with the Brave Community PWA laptop logo method

How can I install a site as an app with Brave?

I know the normal path to save a page as an app, is to click on the laptop logo in the URL bar, or go to the three line menu, Save and Share, and then select "Install site x. Does this mean, that if those options are not present, that Brave cannot do this? I would like to save wsj.com as an app to be opened in the Brave browser. Some months ago, I was able to do this with Edge, and I have an app for WSJ.com on my Windows 11 start menu, that opens in Edge. I’d like to view the site in Brave.
