How to see all activities using the API?

Hi,

I’m using the Activity API OCS and I see only the last few days of activity, whereas in the web panel all activities are loaded when I scroll down.

curl -u user:password http://mynextcloudIP/ocs/v2.php/apps/activity/api/v2/activity?format=json -H "OCS-APIRequest: true"

How can I fetch all the activities using the API?
