Mutate state tutorial: An error "Cannot read property 'sm' of undefined"

[LukaszGrela]

By using the get**Scheme methods I see the Cannot read property 'sm' of undefined error thrown at DrawerSidebar component.

Mutating the scheme:

const standardScheme = getStandardScheme()

standardScheme.configureEdgeSidebar(builder => {
  builder.update('primarySidebar', config => {
    config.sm.collapsible = false;
  });
});

Fails with object possibly undefined (sm), then when it is assured that it exists if(config.sm) it throws error that collapsible does not exist:

Property 'collapsible' does not exist on type 'Omit<EdgeSidebarConfig, "id" | "anchor">'.

It looks like the EdgeSidebarConfig is missing the CollapsibleSidebarConfig, I guess it should say:

export declare type EdgeSidebarConfig = PersistentSidebarConfig | PermanentSidebarConfig | TemporarySidebarConfig | CollapsibleSidebarConfig;

TypeScript: 4.2.3 @mui-treasury/layout: 4.5.0

Can you provide the code that I can reproduct?
