Pairwise t test (holm correction) with ezANOVA output

Question

I'd like to perform post-hoc comparisons using the pairwise.t.test function in R and the output of the ANOVA I performed with ezANOVA but I don't know how. I'd like to perform post-hoc comparisons for the group factor (3 levels).

Here is the code for the ANOVA

anova_age = ezANOVA(data = data_age_anova,
                       dv = age_years,
                       wid = participant_id,
                       between = group,
                       type = 3,
                       return_aov = T)

How shall I use the pairwise.t.test function after that?

Thanks a lot
