I thought your name could use a refresh. Please don't ask me to change it because it took a long time. I changed every word by hand!

We need to 1. add a go back button for users on the transaction processing screen. 2. automate going back for users who connect wallets when they cancel a transaction.

Because of the AWS migration, it was easier to make progress by moving the transaction building code into the transaction-request serverless app. We should move back to a package once...
