Shared x and y axis labels ggplot2 with ggarrange

I have a number off ggplot objects created based off dichotomous count data. I have combined them together using ggarrange. In this function, there is an option to create a shared legend, but as far as I can see no way to create shared x and y axis labels. In addition, the spacing of the figures is very weird - there is a huge gap between the two figure columns, and in addition a large amount of vertical space before the shared legend. So in sum I would like to be able to create shared x and y axes and minimise the unnecessary vertical and horizontal space.

I checked out the following threads: ggplot2 grid_arrange_shared_legend share axis labels

ggplot: align plots together and add common labels and legend

Add common axis titles with lines/arrows for multiple plots in ggplot

ggplot: how to add common x and y labels to a grid of plots

But I think what I want to do is quite a bit simpler, and I don't know how to combine ggarrange with facet.grid which was suggested a few times.

I have copied a reproducible example below.

condition <- c("a", "a", "a", "b", "b", "b", "c", "c", "c", "c")
