How can I use the library Utilitites in typescript

Question

    const signature = Utilities.computeHmacSignature(
        Utilities.MacAlgorithm.HMAC_SHA_1,
        signatureBaseString,
        this.getSigningKey()
    );

This is an example of what I need to implement in typescript but I need to replace the library Utilities.

A solution for the computeHmacSignature in typescript.
