Generated JWT gets Invalid Signature in jwt.io

I'm trying to access a site that requires a JWT to use it's API.

So I wrote this code in order to generate it:

library(jose)

secret = "ed577ae6d3661fec225c24"

jwt = jwt_encode_hmac(
  claim = jwt_claim(
    exp = as.numeric(Sys.time() + 300)
  ),
  #secret = hex2raw(secret), 
  secret = openssl::base64_encode(hex2raw(secret)),
  
  header = list(
    id = "643716473b35aa003d3d6")
)

The resulting JWT is:

> jwt
[1] "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiIsImlkIjoiNjQzNzE2NDczYjM1YWEwMDNkM2Q2In0.eyJleHAiOjE2ODEzNTk5MzAsImlhdCI6MTY4MTM1OTYzMH0.qf8frkpXOGhoe3_LJF4Xls6QFlWloG5qQsAf9gSN-rM"

When I paste that JWT into jwt.io, I get Invalid Signature.

I've tried not encoding to 64 and I've also tried charToRaw but got the same Invalid Signature.

Any ideas?

Thanks,

Your secret to enter are the 7Vd65tNmH+wiXCQ= octets. Because your code takes "ed577ae6d3661fec225c24" the hex octets, decodes them to raw, then encodes them into base64 as the secret).
