How to create a measure from a streaming dataset in Power BI ?

Hi Guys,

Newbie here, is there anyone here who can help me to get the last task based on the date using a measure and show it in a card ?

My datasource is a streaming dataset feeding data from power apps.

OR

If its possible to create a URL filter that will show the same output. That would be match better as I want to show the last task entered by the user thats been using the app.

Thank you so much guys!
