Automatic code signing still attempts to use a certificate uploaded to Bitrise

[AlexeiTU]

Answering my own question here with a post that bubbled up from a few years ago:

xCode Archive gives error with automatic_code_signing

Hey, I would like to use automatic_code_signing and I uploaded my .p8 file to bitrise but still I got error says: issue with input: failed to parse certificate URL and passphrase inputs: code signing certificate URL: required input is not present

TLDR:

• should still upload a development certificate to Code Signing tab
• without this (according to discussion in linked thread) a new dev certificate would be created for each new build, which is typically not what you want.
