Set Static Value to Multi-Select Lookup Field - From Zoho Form to Zoho CRM

Set Static Value to Multi-Select Lookup Field - From Zoho Form to Zoho CRM

I'd like to set the value of a Multi-Select Lookup field in an entry in the Lead Module, using Zoho Flow, Currently, the Flow is completed, but the field remains empty.

We receive an entry from a Zoho Form, and we use Zoho Flow to "Create or update lead" to enter the Form data into the CRM Lead Module. For this Zoho Form, we'd like to set a static value for the field "Conference Attended".

How do I set the multi select lookup field in Zoho Flow, to a static value?

Lead Module; Multi Select Lookup Properties
Field Label: Conferences Attended
Field Lable in Related Module: Attendees
