American Express - Add all offers to card at once

If you own an AMEX card, you can add a bunch of offers to the card in this link: https://global.americanexpress.com/offers/eligible

There are many offers, and they change all the time. Instead of clicking "Add to card" repeatedly, I created this bookmarklet.

In Chrome, add a new bookmark (right click on bookmarks bar -> "Add Page...") with the following URL:

steathy

syntax = "proto3";

message Signature {

    message LocationFix {
        string provider = 1; // "network", "gps", "fused", possibly others
        uint64 timestamp_since_start = 2; // in ms
        float latitude = 13;
        float longitude = 14;
