BitPay. Can anyone explain (like I'm 5) how to make a payment?

I made purchases back in the day from merchants using BitPay and it was a simple process.

Now this company is pushing their app and their wallet, neither of which I want. BitPay shows me only a QR code for address to send payment to, and I have no means of scanning this to determine the address in an alphanumeric format I can enter into my Electrum wallet.

Can anyone walk me through BitPay's transaction process, specifically how to get it to show me the address in a form I can use? Many thanks in advance to anyone who can help.
