How to add my MacBook To Find My

I purchased a M3 Macbook Air just before the launch of Sequoia. When the OS update was available I updated it. During the startup process, it prompted me to bind the MacBook in Find My to an account. For whatever reason, it decided to bind to my wife's iCloud account. Well after trying a few steps to remove the Macbook from her Find My, I finally just deleted her user account off the Macbook, which prompted for her password to remove it from Find My. Now, I'm trying to add it back to my Find My and it won't let me. I am in the device info on the Macbook and it will not let me click on Find My Mac and switch it to on. Why is this process so difficult? It should never have defaulted to my wife's account for Find My or given me an option to skip it when I set things up after the update.
