Add a "payment method" token for use in order e-mails

Hello,

I created a rule to send an email to a "product owner" so they can see a summary of an order. I have just about everything set up, but I don't know how to get the Payment method to show up in the email. I added "Commerce Payment Transaction" as a data type in the rule settings, but I'm not sure what condition to add to bring payment method into scope. "Entity has field" and "entity of type" don't seem to make sense for me.

Any tips?

Thanks in advance!

Here's the rule export:

{ "rules_notify_product_owner_if_field_notify_email_is_present" : {
    "LABEL" : "Notify Product Owner if \u0022field_notify\u0022 email is present",
    "PLUGIN" : "rule",
    "REQUIRES" : [ "rules" ],
    "USES VARIABLES" : {
      "line_item" : { "label" : "Line Item", "type" : "commerce_line_item" },
      "commerce_order" : { "label" : "Commerce order", "type" : "commerce_order" },
      "payment" : { "label" : "Payment", "type" : "commerce_payment_transaction" }
    },
    "IF" : [
      { "entity_has_field" : { "entity" : [ "line-item" ], "field" : "commerce_product" } },
      { "entity_has_field" : { "entity" : [ "line-item:commerce-product" ], "field" : "field_notify" } }
    ],
    "DO" : [
      { "LOOP" : {
          "USING" : { "list" : [ "line-item:commerce-product:field-notify" ] },
          "ITEM" : { "notification_email" : "Notification email" },
          "DO" : [
            { "mail" : {
                "to" : [ "notification-email" ],
                "subject" : "Someone submitted payment for [line-item:line-item-label] on the website!\u000D\u000A",
                "message" : "Someone submitted payment for [line-item:line-item-label] on the website!\u000D\u000A\u000D\u000A[line-item:line-item-label]\u000D\u000A[line-item:commerce_total]\u000D\u000A\u000D\u000A\u000D\u000A\u000D\u000A[line-item:field_contributor_name]\u000D\u000AAd or Memo: \u000D\u000A[line-item:field_ad_text] [line-item:field-memo]\u000D\u000ACustomer info: \u000D\u000A\u000D\u000A[commerce-order:commerce_customer_billing]\u000D\u000A[commerce-order:mail]\u000D\u000A\u000D\u000A~Admin\u000D\u000A-------------------------------------\u000D\u000A[commerce-order:commerce-webform-submission]\u000D\u000A------------------------------------",
