Hi Ian,
Here’s a link to using the drift-scan technique for occultation events
https://www.asteroidoccultation.com/observations/DriftScan/Index.htm
I’ve no experience of using it, and the Betelgeuse event was gradual.
All observers who attempted to observe the Betelgeuse occultation are requested to submit a report form and their raw data to the pro-am campaign team in Paris. This is discussed in Josselin Desmars’ presentation

Create an account on the Occultation Portal
https://occultation.tug.tubitak.gov.tr/
then upload your report file and data (see other methods if files are very large). The Paris team will analyse your data.
