If you would prefer the type string instead of using TypeScript template literal types (released in TS 4.1) then I can make this change.

@karlhorky thanks for the PR.

We'd indeed prefer a string to avoid using TS 4.1, some consumers might still be using old TS versions and thus may run into issues with their tooling.

Once you'll make the change we can review for merging.
