Open App in new Tab

hello
from the frontpage of UCS (i still have no idea what the difference between UCS and Nubus) are the apps.
is that correct that each app opens in a new Tab as a new Page ?
or does the app open in the same app stream like the frontpage

background: if is a new tab, it will be counted as 2 sessions, rather than one session.

i can publish rdp apps there, but do they open as a deperate app or are they open as UCS (so, access from the frontpage or app page).

thx for info
regards

you may set the behavior on opening in the app icon configuration at the portel editor like:

is that than the same stream or is that a second ?
