‘otplib’ library throws TypeError: crypto2.createHmac is not a function error

I’m trying to use otplib library in cloudflare workers but seems like it is not supported because of a crypto/crypto2 dependency, at least that’s what I understood from this error:
Error generating OTP: crypto2.createHmac is not a function
