@Moem thanks but i do not use telegram.
That is why I said: If you don't use Telegram you can read it in a browser. Have you tried clicking or tapping on the link? You'll be invited to view the channel in Telegram, but there will also be a button that says 'preview channel'.

@Moem swipe up in the "calls" app does nothing. Keeps showing the number buttons to dial a number.
Do you see the little grey button with an arrow, just under the green button that you use to make a call?
Drag that little grey button upwards. That should do it.
You'll see such buttons in more apps on UT. If you see one it's worth checking out what it does.
