Looker Filter question [Date Range] Auto Update

Hello?

I'm making a dashboard by choosing the date period
However, the period or date does not change from the date of creation.
For example, I want to do it automatically for the last day.
There's a filter that's been going on for a week recently, but the user is not familiar with it
So I want the dashboard to load and automatically enter the start and last days
If i go into the dashboard today, 8/21~8/27.
If i go into the dashboard tomorrow, 8/22~8/28.

Once I decide, the date doesn't change automatically
What can I do?
