Add additional params /oauth2/token response

Hi everyone!

I’m using JMIX version: 2.1.2

Is it possible to add additional parameters here, response of token request?

I found similar question asked before in the form like “Add more info return in when invoking oauth/token”. But I can’t implement those codes to my own project because of incompatible JMIX versions, I think.

Could you provide another solution to add extra parameters to the /oauth/token response.
