Can I use Response Tokens in offer?

[btorres76]

I have enabled activty.id and experience.name response tokens expecting that I can use ${experience.name} in an offer (or option).  Am I using this incorrectly? Also, when I put the following code in the offer, tokens is empty:

document.addEventListener(adobe.target.event.REQUEST_SUCCEEDED, function (e) {

    var tokens=e.detail.responseTokens;

});
