error message: "Must use import to load ES Module"

[cesarpachon]

hello, adding this library to my project that uses mjs modules (node 14) I got the mentioned error message, code: 'ERR_REQUIRE_ESM'
what is the recommended way to use this library in a ESM environment?
UPDATE: I figured out that it works from the main project, the error happens only when trying to run a jest test, so it is more a issue with jest than with this library..
