String values to Array - To column Expression node ArrayCreate and ArrayContains

Hi friends

How I could do this code using a collection and then passing to an Array Create formula:

Explanation:

I have this values in a column**

My Goal

I want to use this values into this formula: But dynamic

Use an array contains

But, this formula in column expression is hardCode.

What I have tried to do so far…

1) GroupBy - Set aggregation

2) Column Expression - Array create

checking

…then I’m Lost now

Any best ideas?

I don’t understand why, even after creating a column with the data type as a collection, it didn’t work inside my variable.
