Adding a Legend on map

[JasonShim]

I'm using ArcGIS Pro V.2.6. How do I add a legend to my map? I was trying to follow these instructions that I copied from Arc GIS Help documentation. I wasn't able to locate the "Map Surrounds Group" and "Legend" buttons in my version of  ArcGIS Pro. Perhaps, there's another way of adding legends?

"To add a legend, complete the following steps:

1. Open a layout with at least one map frame. A legend can only be added to a layout view.
2. Select the map frame in the Contents pane.
3. Optionally, expand the map in the Contents pane to select a subset of layers. If no layers are selected, a legend is added containing all applicable layers from the map contained in the default map frame.
4. On the Insert tab, in the Map Surrounds group, click Legend . On the layout view, click and drag to create the legend.
5. Format the legend. See Arrange a legend for information about formatting options."

Can someone help please ?

Add Layout View first, then add a map frame to the layout. Then you can add the Legend from "Map Surrounds" group
