HTTPConnector - Not able to send bearer token in cloveretl httpconnector

Question

Code Transformation

function integer transform() {
    $out.0.requestContent = $in.o.json_file;
    $out.0.charset = "UTF-8";

    $out.0.URL = "https://api.abcd.com/applicationname/apiname";
    $out.0.requestMethod = "POST";
    $out.0.oAuthAccessToken = dictionary.TOKEN;

    return ALL;
}

I am working on building a clover graph. My goal is to get the bearer token by calling http connector using authentication - 'HTTP BASIC' first and then use this token to call other APIs. I am able to accomplish the fist part but unable to pass the token as there are just two authentication methods available - (HTTP BASIC, HTTP DIGEST). Any suggestions on how to achieve second part would be greatly appreciated.

CloverETL - 4.4.0.11

I got the token stored in a directory

graph is expected to post the JSON data to the api using bearer token
