Qlik Sense - Using Button how to select Multiple values in a Field

[YG]

Hi All,

I am pretty new to this and I have found multiple answers to this question but non of it seems to work on Qlik Sense Enterprise version for me.

I have "Button" and I want multiple rows (characters)  selected when pressed. 

Simply I want to select =  "1 - Critical"|"2 - High" when pressed.

So far I tried, 

1. ='("1 - Critical"|"2 - High")' - Did not work

2. ='(1 - Critical|2 - High)' - Did not work

3. =(1 - Critical|2 - High) - Did not even validate

However, If i try just 1 selection it works fine, That is  ='1 - Critical' 

To explain more I have 5 selection so Alternative selects are not an option for me too

Thank you! I've been trying so many combinations to make this work and it just wouldn't. To anyone wondering, this also works for wildcards. 
='("*1 - Critical*"|"*2 - High*"|"*3 - Moderate*")'
