Scattering Seeds - Will this work?

Hello there,

I'm new here and a total gardening novice, so please forgive my
ineptitude. I've heard people talk about scattering seeds and then
flowers growing up from them. I have some overgrown grass in my garden
that I would prefer to be some  wild flowers and have a spare packet of
wild flowers that includes field cornflowers, field poppies, ox-eye
daisies, cowslip and foxglove.

If I were to sprinkle these seeds around the grass, is there any chance
that they would grow/flourish? Would it help if I mowed the grass first?
Or would I have to disturb the soil first/remove the grass/go through
the normal seed growing routine?

I live in Buckingham****re and like the rest of England, it is insanely
sunny at the moment

Thanks for any feedback!
