So looks like there's an epic open for this, but it is not implemented yet:
https://github.com/airbytehq/airbyte/issues/12089
I'll try to find out where this is on the roadmap, but cannot give you concrete dates right now.
At this point if the schema changes, I believe you need to do a full reset - run a full refresh sync. This will result in the loss of historical data unfortunately. I'll research this further early next week and let you know if I find any other workarounds :)
