ukulele tabs

HI all I am new to this, and not sure how to go about it.
any way I have downloaded a score from muse score for ukulele (I walk the line)
I would like to add the tablature for the low G ukulele.
before in Muse score 3 I just typed [i] and got the window with the add instrument and this allowed me to add a linked stave
try as I might, I cannot find this in muse score 4 if I type [i] I get the add instrument window but there is no option to add a linked stave?
any ideas any one?
