Azure Data Factory: How to implement change feed in data flow?

I am building a pipeline to move data from CosmosDB to Delta table. ADF supports change feed for CosmosDB by default ONLY IF I select Container as input in the source. Due to requirements I have to use Query as input and as a result I can't select change feed in the source. What's the alternative way to implement Change feed in data flow? I would like to be able to upsert (and possibly delete) records into the delta table.

Currently I am using the Alter row modifier and set Upsert to true() in the alter row conditions section. And this modifier is piped from the source data. Not sure if this is the correct implementation.
