I got a MacBook used by an other employee of my company.

On XCode when I go to Settings > Account > Selected item in Team > Manage Certificates I have 2 certificates in the category Apple Development Certificates where the creator mail is mine:

• MacBook Pro of XXX
• company’s iMac Pro

Both are disabled with status Not in Keychain

I can’t create a new Development certificate because I got the error:

You alreay have a current Development certificate or a pending
certificate request.

How can I remove those 2 certificates ? I didn’t see anything of developer.apple.com

Thanks
