I am using record choice set to get all related files in a lightning flow. I want to display name of the files in a multi select picklist from where user will select some files. I am trying to get ContentDocumentLink for a related case. In order to show file name I need document.title with the contentDocumentLink recods. I can not use apex because I will be using this flow in FSL mobile app.
Is there any way by which we can get merge field value.
Please refer the below image where I need to display file's name in the available list instead of the document id.
