Hey @gauravparajuli09
As long as there is a map/database that the Survey123 information is written to, you can use that map/database as datasource for the Dashboard, this would allow the Dashboard to be updated with current information that was collected out in the field.
You would need to first set up the Survey123 survey and deploy with the information you want to gather. Afterward, you'd need to check the feature layer created and see that the attributes are present, then create the Dashboard and add the data source as the Survey123 feature layer that was created, you'd then have access to all the collected data there.
