Hi,
I am quite new to power apps and need some guidance. I have created a SharePoint list and I have exported it into a power app where you can see the rows of the list:

This SharePoint list will be updating over time with new items added. Each row has a column for a start date.

Currently the gallery view is showing all the items in the SharePoint. How can I make it so that it only shows items that are todays date. So if an 5 items on the SharePoint have a date that is 01/01/2022 and on 01/01/2022 only those 5 items will be listed on the power app, and the next day if I have 2 items with a start date of 02/01/2022 only those two items are shown.
This is current the formula written is: This just has the gallery view a descending order

The powerapp also has a details screen where the date is located:

Can anyone please provide some guidance as to how I could achieve this?
Thanks,
Henry
