Salesforce connector import data from pervious activity ids.

Hi,

Need help,

In the salesforce connector, we want to select only those customer ids which we will be able to pass from previous activity. This can be multiply ids at a time and we need to pull only that customer's ids from salesforce.

These customers will be dynamic daily it's not static.

How can we use the below step to use the population calculated what needs to be used in the field containing the remote identifier I tried to use salesforce id as [@salesforceId] and also tried [target/@salesforceId] but no luck and the field picker icon is also not working.
