Need access to FilteredActionList to create a stopgap modal SelectPanel #4840
Description
I am attempting to implement a design that involves a 2-step modal dialog with a list that can be filtered.
This is very close in design to SelectPanel "v2", however there are some limitations with the v2 component, and after chatting with the Primer team I've since learned the v2 design is being abandoned in favor of making the "v1" SelectPanel accessible (since apparently folks preferred the v1 usage pattern).
The "v1" SelectPanel does not support a modal version (and I'm uncertain whether it would allow me to create the 2-step process I need from the design that I was able to "hack together" using the "v2" component.
To that end, I would like to create my own custom Dialog using the same filterable list used in SelectPanel. After talking with the Primer team this was revealed to be FilteredActionList. Exposing this component will allow me to create a modal dialog satisfying my design requirements until SelectPanel "v1" has reached a level of maturity that would support my use case.
