Pattern 3 column card buttons alignment

Hi,

I am trying to set up a shop and used Neve FSE Pattern to create as per below. The problem being I would like everything to align the buttons regardless of the amount of text in each column.
I have tried custom code to no avail, I downloaded a plugin but I can’t get that to work either. Any help would be appreciated.

Just realised I can’t add standalone images here. I published the page just for the purpose of getting help I’m still working on layout hence two different ones. Hopefully you can see what I am trying to achieve.

Thank you.
