Problem linking existing Thunderbird calendar to Google Calendar

For many years I have had a Thunderbird Calendar, and have a large number of Tasks set up in it. I have now decided it would be convenient to link it to my Google calendar, so that it also shows on my new Windows 11 machine and on my laptop. I've gone through the process described in the "Create new calendars" article, to link the calendars, and the Google calendar is now appearing in the Thunderbird calendar, but not vice versa. How do I get the Tasks in the Thunderbird calendar to appear in the Google calendar?

I am running Thunderbird 140.7.1esr and Firefox 147.03 on my Windows 10 machine, which I used to set up the link. My Windows 11 machine has the same Firefox build, but Thunderbird 147.0.1, and the Google calendar display is the same, but I haven't yet set up the Thunderbird calendar on the new machine.

You can export your local calendar to an ICS file (right-click on the calendar name in the left panel), then import it to your existing Google Calendar (in Windows, Main menu | Tools | Import | Import from a file | Import Calendars.)

I don't if it's possible to do it from within Thunderbird, but if you want two separate calendars, you could create another new calendar at your Google Calendar web page and import the ICS file there, then Subscribe to that calendar in Thunderbird alongside the current one.

Unfortunately this only imports Events, and it is Tasks I need to import.

So far as I can see the Provider for Google Calendar, which sfhowes recommended appears designed to show Tasks which are in Google in the Thunderbird calendar. My problem is the other way round - I have them in Thunderbird, and want to show them in Google.

If you create a new task in the Provider calendar, does it appear in the Google calendar on the web or other devices after syncing? As for existing tasks that are stored in a local TB calendar, I think the only possible way to add them to the Google calendar would be to export the local calendar (Events & Tasks/Export...) and import it to the Google calendar. But that's just speculation, as I haven't tested it.
