Sync with Google Calendar – change in code

Hello,

We were speaking in this topic: https://wordpress.org/support/topic/import-whole-calendar-into-google-calendar?replies=5

I have one more question. Where can I change URL of “Export Calendar” button under choosen month? I want to change this URL so events can be synced in Google Calendar. I can’t find any function.
