Description
Is your feature request related to a problem? Please describe.
We don't yet have the option to set the types for data passed as events or context entities in our track functions.
Describe the solution you'd like
Extending on issue #1249, we can add the type argument also to the track functions (trackPageView, trackSelfDescribingEvent, ...) so that users can specify the types for the self-describing event or the context entities.
Additional context
This runs into a problem that we discussed with @igneel64 that we need to change the type of the self-describing data from Record<string, unknown> to Record<unknown, unknown>. This should not be a breaking change, but can be in case people set TypeScript expectations on the types, which is probably rare.
