Export MS ToDo from gmail account?

I set up a MS ToDo with a gmail account.

I now have a microsoft account as I want to use the TimeBlocking function from ToDo in Outlook.

I therefore want to export that gmail-based ToDo into the new MS account ToDo.

I have quite a lot in it so don't want to have recreate every list.

Googling seems to suggest I can only export from an MS account within Outlook - the Export My Data in the android app takes me to a website showing how to do it in Outlook. And in Outlook when I try, it says "You can't export email calendar items or contact for nonOutlook mailbox here." (this the 'new' outlook in Windows 11).

Surely there is a way to export all my ToDo lists and tasks from my gmail linked MS Todo!!
