Ok thanks, I wasn’t even close to imagining this was the issue.
The short answer from me is I don’t actually know if you can.
I have done some researching though and I am doubtful at the moment if it is possible. (I’m hoping I’m worng but this is just my view from what I have read)
The detail in this web page provides the most info
Specifically this part
Does seem like there’s a reasonable limitation to using this at the moment
