Opening WhatsApp links in WhatsApp Web in Chrome (Flatpak)

I want to share links on WhatsApp Web.

What I expected

When I click on a WhatsApp share button on Firefox (e.g. go to a youtube video → share → WhatsApp) it opens a screen with a button “Continue to Chat”. It detects that I don´t have an desktop app to open the link and it offers to go to WhatsApp Web. I click on the suggestion, and it takes me to WhatsApp Web correctly. I expected Chrome to behave the same way.

The Problem:

On Google Chrome (installed with Bazaar, version 138.0.7204.168), I tried doing the same. When I click on “Continue to Chat” it offers to open with xdg-open.

I tried the following:

  • Clicking on “Cancel”. This just closes the dialog box.
  • Opening the app with xdg-open and selecting Google Chrome. This opens a new Chrome window, empty.

But there was no way to get to WhatsApp Web. What am I doing wrong? Does someone know how to fix this issue?
