How to clear orders in "Recent Orders" list on Alpaca Dashboard?

Hi, paper trader here.
I am trying to clear filled orders on “Recent Orders” list on Alpaca Dashboard.
I select orders by checking the box to the left of the order. then click the cancel tab.
But it does not take effect.
The reason I am trying this is to limit the number of recent orders that show up in the response to
string ordersUrl = “https://paper-api.alpaca.markets/v2/orders?status=all”;
The debug printout is cluttered with many old orders.
Are there other qualifiers than all in status that would limit the response to for example orders today or the last 4 orders?
If you could also point me to the Alpaca web page that describes this that would be nice.
This is the page I found:
Working with /orders
But, I think there is another page of docs that describe in words.
Thanks!

I am unsure because I don’t use paper trading but couldn’t you modify the ordersUrl for last 4 orders:
