jamovi

epsilon squared (Tomczak and Tomcszak 2014).
k = kruskal.test(dv ~ iv, data = data)
k$statistic * (NROW(health) + 1)
/ (NROW(health) * NROW(health) - 1)
(used in my R book - https://vorpress.com/r/index.htm)

Alternatively, you could look up any given book's entry on Amazon and use the 'Look Inside' feature. That will show you a few pages.

University teachers can ask for an inspection copy:

Hi. Using version 0.9.0.5, I now find that the retain levels option no longer applies for 'filter'.

Well, you will find references to the Holm-Sidak correction. I would feel happier, however, if one or two other people checked this.

Isn't the Sidak another name for the Holm? (Find the smallest p value and multiply by the number of pairings; find the next smallest and multiply by the number of pairings minus 1; and so on.)
