Do you see 'Header', 'Aside', 'Article', 'Section' and similar HTML5 semantic tags in the 'Insert' box? It came out with 12.2 Creative Cloud update.
Those have replaced a regular 'Fluid Grid DIV' in the Insert panel. These tags are already, by default, a Fluid DIV tag - as defined by your doctype - HTML5 when you create a new FG Layout.
