Align button to bottom of row

[CSharpDummy]

Question

I have a simple alignment q. I have a button element in a row and would like to align it to the botton:

with ui.row():
    ui.button('update', icon='o_not_started', color='positive').props('flat')

But it sticks to the top of the row. Any idea what to do?

with ui.row().classes('h-96'):
    ui.button('update', icon='o_not_started', color='positive').props('flat').tailwind.align_self('end')
