Can't find plug-in inside Adobe Premiere Pro

Recently my computer got wiped. Today, I downloaded the updated Seamless Transitions v6.5. I downloaded and installed both Aescripts ZXP Installer and Seamless Transition Setup.exe. Once I restart and reopen Adobe, I go to Windows - Extensions. Seamless Transitions shows up as the directions say but nothing happens after I click it. There’s no prompt for a license number nor does Seamless Transitions appear in my workspace. I’m running Windows 10 and Adobe PP 2023. Can you help?
