Safari Extension not found under Catalina

[Former user]

Bibsonomy's Safaro extension seems to be lost. Using MacOS 10.15.5 (Catalina) with Safari Version 13.1.1 after pressing the "Download Safari Extension", one is directly routed to Apple's website:

Additionally, the App Store app opens and displays all extensions, but Bibsonomy is missing.

Currently the extension link points to the old plugin and Apple is redirecting the link to the Mac App Store. But we have currently no extension for Catalin or Big Sur.
