Show signature field on agent mobile app does not add the signature in the record activity streamDescriptionThe show signature field on the [sys_sg_button] table does not record the signature in the activity log.Steps to Reproduce The intention is to create a top menu action called as resolved, which will set the status of the incident to resolved, and add a picture and signature: 1. Create an applet (table incident).2. Create a data item.3. Create an action item.4. Create Action resolve incident.WorkaroundThis is expected behaviour. The "Show signature field" checkbox in the sys_sg_button table is designed to perform the following when submitting an action: 1. Create a record in the signature_image table;2. Upload the signature image to the sys_attachment table associating this attachment to the signature_image record just created;3. Set the "table" and "document" fields in the "signature_image" table to point to the "table" field configured in the sys_sg_button and the record that was created/updated by the action, respectively. By design, since the signature attachment references the signature_image record, it will not be displayed in the incident activity stream.Related Problem: PRB1350028
