How do I get the assignment history for a task?

Hi,

I'm about the pull data from the API to build a custom SLA report for a client. One rule is that a task has to be assigned to a developer within a specific time.
So I need to find out when a task has been assigned.

From poking around it looks like I might need the "Change" type to get such historical data. I can get a list of changes from

/api/workspaces/<id>/changes

but it looks like it always gives me the latest 100 changes and that the filter[] query string does not apply.

So - is there a way to do what I want?

As a plan B I've considered to subscribe to webhook messages and buld a change storage myself, but it would be easier to just query the Liquid Planner API.
