Plaid plugin server side response

I am working on the development of the plaid plugin, and I want the access token to be generated on the server side, instead of the client side . but I am not able to retrieve the access token, by using the server side action functionality of the plugin editor, so is there a way to accomplish this task.
@emanual-emanual , if you can assist me.
