Layers in Sketchup Pro 2019 version

I am not able to View additional options in Layers Toolbar - like adding and deleting layers, switching layer on and off.
We have a subscribed commercial verson of Pro 2019.

Look for the layer dialog in the default tray.

checked all toolbar options.(as you shall also see below). Layer tab still has no other option in it. :frowning:

Go Window menu and turn on the default tray.

Got it
Thanks & Lot!!
