ggplot2 - Is there an option to limit the presented axis values in a ggplot with significance label without cutting them off in R

Question

I'm analyzing numeric data with values between 1 to 7. I want to plot boxplots and show the significance across categories. My problem is that adding the labels also extends the values in the y axis. This might imply that the possible data range is up to more than 7 - which is not the best. I tried using ylim() but using it cuts off the signif labels. Is there a way to make the axis values to be 1-7, without cutting the information the should apear beyond this range?

my current plot:

when using ylim()

the desired outcome is something like that:

As mentioned in the comments, the solution is setting breaks: gboxplot(...)+ scale_y_continuous(breaks = seq(0, 7, by = 1))
