Where is the 'Setup' page as described in documentation

I’m trying to follow this documentation from https://erpnext.com/docs/user/manual/en/customize-erpnext/hiding-modules-and-features ERPNext documentation page. But i can’t find a page called ‘Setup’ or ‘Show / Hide Modules’.
Anyone please help me to hide dekstop icons.

But tabDesktop Icon table is empty.
What i’m trying to achieve is hide system modules like Selling, Buying, Getting Started and CRM from desktop

Hi @anastes,

Login as the System user.
Go to Setup>User>Select the user whose desktop icons you want to hide/show.

Check the screenshot below for more clarity:

Then select the icons you want to show/hide.
