As part of this guide, when I try to upload the p8 file I see this error:

"Invalid file name, it should be SubscriptionKey_XXXXXXXXXX.p8. A file name with any other prefix could be a private key for a different Apple service. Please validate you are uploading a Subscription Key."

The file I downloaded from App Store Connect is called “AuthKey_XXXXXXX.p8”. Am I supposed to manually rename it or have I downloaded the wrong file?
