Persona with custom presence icons?

[GordonSmith]

Are there any examples of using Persona with custom Presence Icons?

[TheColdPot]

Persona has a presence prop. It's type is enum PersonaPresence.
If you want to add an icon with a presence,

<Persona
    {...OtherPersonaProps}
    size={PersonaSize.size8}
    presence={PersonaPresence.online}
 />

PersonaPresence has following values:

away     = 3
blocked  = 5
busy     = 6
dnd      = 4
none     = 0
offline  = 1
online   = 2

Fluent UI cannot having custom image for presence yet. You can submit an issue or raise an idea.
