Hey msmetzger5,
Sounds like you need help getting Find My enabled for your Beats Studio 3. To do so, you'd just need to pair them to a device that has this feature enabled. If you have Find My enabled for the iPhone 13 Pro you paired them to, try resetting them and checking again.
For help with doing so, complete these steps:
Reset Studio3 Wireless
1. Hold down the power button and volume down button for 10 seconds.
2. When the Fuel Gauge flashes, release the buttons.
Your headphones are now reset and ready to be set up with your devices again.
This is outlined further here: Reset your Beats on-ear or over-ear headphones - Apple Support
Set your Beats back up again with the steps here afterward: Set up and use your Studio3 Wireless headphones - Apple Support
We hope this helps out.
Take care!
