Hi Mike,
If you need read access to your data, you could try OdataLink. I'm the lead dev there (so biased :-)
https://odatalink.com/
https://www.myob.com/au/apps/odatalink
It's aimed at non-developers. It's a tool we built that directly integrates with excel/powerbi/fabric by way of odata and "fills the gap" where people need access to their MYOB data to analyse things.
We plan on also adding write-back access so you can push data straight through to MYOB. And the end goal with this is for our stuff to be used through Microsoft Power Apps/Power Automate.
To be fully unbiased, we are not the only ones in this space so you can check out the app marketplace for others.
