Beaver Builder, how can I align buttons in a advanced post module?

Question

How can I align the buttons in a UABB advanced posts module, as shown below. Using css Flex breaks the lay-out. Wondering if it's possible

enter image description here

Tried to use: { display: flex;justify-content: center;align-items: flex-end;flex: 1 1 0; } On the button, but that does'nt work.
