Export membership data via API

Hello Asana Community,

does anyone have an idea if and how it might be possible to use the handy “Export membership data” feature from the API?
I’m especially interested in gaining insight into the last activity date of our users.

Many thanks in advance,
Sebastian

EDIT: I’m aware of “organizationExport”, which however is more data than needed and only available once every 5 days, while “Export membership data” does not have such a limitation.
