I don't totally know why, but sometimes there is no link to the executed transaction for admin actions. Sometimes there is, but sometimes there isn't. I think maybe it happens just after a certain length of time? Or maybe when I wasn't the one who actually executed (and only signed)? I'm not sure, but here's an example of one where it clearly executed, but simply no link( https://defender.openzeppelin.com/#/admin/contracts/mainnet-0x4eb844Ff521B4A964011ac8ecd42d500725C95CC/proposals/5ea05a7f-17f5-4398-8d62-189b5f8ecfa2)
