Hi @maradonathealexandri Welcome to Auth0 Community
I don’t have a JWT lib in JS code to provide you on my own but have you checked jwt.io libraries section to see if any of the JS libraries mentioned there could use your help to add support for those algorithms? Another suggestion (and I’m sure you probably already did this but) would be to just do a npm search for jwt and find a library there to add support jwt - npm search
