How can I check if column is visible or not in the data grid?

[tshailesh-vmw]

I have a datagrid and I want to know which columns are visible or not after user uses hide/show feature of the datagrid but the values are not reflected back to the variable.
Is there a way to achieve this?

Here is a stackblitz reproduction of the same. I am using clarity 3 and angular 9.
