I think providing an option within the Map Layers Widget in Experience Builder that would automatically show the layers symbology when ticked on would make this app easier to use/understand from a member of the publics perspective.
At present it is rather convoluted having to use the Legend widget separately or using the Show Legend option within the Map Layers widget which then presents the hamburger icon requiring further expansion.
So for example user ticks layer on and symbology for that layer rolls out underneath. Tick layer off. symbology goes away.
