What is the desired functionality that you are missing?

The ability to view a list of all entities of a particular type

Which problem are you going to solve with this functionality?

Without list capabilities

Context: Given, When, Then

GIVEN I am an Optimize user
AND I have API access
THEN I can retrieve a list of Collection IDs

BUT if I do not have access to a given entity
THEN it is not provided

Hint:

I see no reason to significantly modify the payload from our internal APIs
We should copy existing behavior and patterns as much as possible
99% of customers will have less than 1k entities
