When this plugin is enabled, it will show past daily or weekly notes from the associated daily/weekly note. For example, if you have a daily note from 2023-07-01 it will show you the daily note from 2022-07-01 as well as previous years (if there are any). While lookling at weekly notes, it will show you weekly notes from previous years with the same week number.
This plugin can be installed directly within Obsidian. Be sure you have the Periodic Notes Plugin installed and configured correctly. As long as this plugin is enabled, it should function. If you have an issue or don't love it, let me know in Github issues!
