Process to execute adhoc snapshots in Mongo Src connector

Hi Team,

We have our Mongo connectors setup running in production.

Now we got the requirement to read one more collection in the connector.

If we add the table to the existing connector, the connector won’t process the whole data right?, it will process only changes for the new collection too.

Postgres SRC connector has signal table, from where we can execute snapshots.

Can you please let me know, if we have something like that for mongoSRC connector.
And the startup mode, we are using in the connector is “copy_existing”
