I am in Wayland session and when I click in one external link of Steam, opens the link in Firefox but don't bring the browser to foreground.

For this is necessary xdg_activation_v1 protocol.

Post of Nate Graham, developer of KDE:

Steps for reproducing this issue:

1. Click in some external link. Like the Activision or Xbox in this official thread of Sekiro: https://steamcommunity.com/app/814380/discussions/0/1850323802576197652/
2. A new tab opens in Firefox but Steam is in foreground (and Firefox in the background) instead bring Firefox to foreground.

Expected: Firefox goes to the foreground when I click an external link in Steam.
