Create a new column with the text of another column between parentheses

I am new to Power BI and I am trying to create a new table column based on the values of an actual column in the table, between parentheses.

Actual column = Frankfurt (FRA)
New Column = FRA

Can somebody help me please?

>Solution :

In PowerQuery, select your actual column, then go to Add Column tab in the ribbon, and select Extract > Text Between Delimiters. The add ( for start and ) for end.
