Custom Actions using Flow

I wish I could have found this in the documentation.

I have done some experimenting and have figured out some limitations in using custom flows in the Action Builder.

If you have any of the following types of variables defined for Output, none of your output attributes will show up in the Agent Builder

• Currency
• Picklist
• Multi-Select Picklist

All of these other types seem to work with no issues, both for standalone and collection versions

• Text
• Record
• Number
• Boolean
• Date
• Date/Time
• Apex-Defined
