Switch case for mail

Hi,
I need to run the bot for the different subjects of the mail eg: 1 is Lead, the other is contact and the other is Business so these will be my subject where I need to identify the subject and download the attachment. For this, I need to use a switch case which would be the efficient one. How could I pass the expression? could anyone help me

For this you can use if condition or switch case activity.
