Randomizer Unique ID for new collection record

I want to assign an unique ID for every new record that is added under a user. For an example, the user will add a new child to their account, I want each child to have a unique id number assigned.

How can I do this with randomizer? Is it even possible?

Yes, this is possible to do with Randomizer. But I don’t recommend this component because not everytime is working. If you want to use a custom action to generate an unique ID feel free to send me a message.

Thank you for responding, I was able to make what I needed to work with the RAND function. Thank you for being willing to help me.
