Zoho Analytics and Databridge - the instructions do not match the install process - can you help please.

I have databridge installed & running in windows and

I can connect through Settings> Manage Databridge - it is active.

The instructions say I should go to Data Source > Local File

but these instructions only fit the Database selection -
when I go to the Files option I do not get the databridge when using the Excel/CSV

I am trying to import a large CSV file
(no other format options are available)

What am I doing wrong please?
