export * from "is-what" No type export

[biggerstar]

For example, I am packaging a toolkit for my own use,
using export * from "is-what"
can not export all types and pass them through to the new package, although there is no type prompt,
but js functions can be used normally
I wonder if this is a type definition flaw in Is-what

@biggerstar is-what latest major version is ESM only. Your project must enable ESM by adding "type": "module" to package.json.

If you share a minimal reproduction I can look into it!
