I successfully linked / synced the thunderbird calendar with the iCloud calendar. Calendar entries manually entered in iCloud or iPhone calendar are successfully synced and are visible in the thunderbird mail. The other way round, syncing the existing entries in the Thunderbird calendar does not work. They do not appear in the iCloud or iPhone calendar. Searching the internet, the specific Thunderbird or Apple help-sites did not provide an obvious solution for this problem. I went through all (or nearly all) recommendations given by Apple, no success to sync from Thunderbird to iCloud.

Any suggestion what to modify or adjust

Problem Initiating New Calendar in Thunderbird 140.12.1esr. Currently sharing calendar information between two accounts, both from Google calendar. Syncing between Google and Thunderbird has been working smoothly. Recently added KC Chiefs schedule to Google calendar. The KC Chiefs schedule displays correctly in Google, but does not display in Thunderbird. Attempts to add the Chiefs schedule directly to Thunderbird using the indicated (Google) 'Integrated Calendar' links fails. How do I obtain an .ics file to add this to my Thunderbird. Additional thoughts, my system is Linux Mint, and I am currently operating behind a VPN. Thanks,
