Adding a trace precedents button to standard toolbar

I’ve been an excel junky to date, but I’m considering a move to libre.

I’m trying add a trace precedents button to my standard toolbar. Is there a button for it that I can’t find? or, do I have to create one using the menu item (tools/detective)…etc.? If so, how do I create a button out of a menu item?

I found the button and added it to my standard tool bar. I does not, however, have an icon so it’s just text. Would be great if an icon were available.

It is possible to add the button to a toolbar.

Menu/Tools/Customize/Toolbars.
Here you can create a new toolbar or add the button to one of the standard.

After press the button Add look in Category/Options.
