Journey Physical Signature

Summary:

Hi,

We are trying to use a new feature from 24B for Journey, allowing users to provide physical signatures in the Journey task.
The document says we need to include column ESIGN_SIGNATURE, but which content should we write for this column in the query?
I tried several ways but with no success.

Regards
