How do I italicize a field when updating a bibliography template?

How do I italicize a field when updating a bibliography template?I am working on a Mac and there are no text/font icons to use (i.e., italics, bold etc) like all the online advice suggests.

To italicize a field in the bibliography template 1st, select field, then go to the top of your output style which displays a variety of format settings. Click the “I” to italicize (see attached image).

I think it works differently on a Mac.  See this thread - although I am not on a mac and can’t check if it is still the case.
