Show Guild Member promote frame from lua?

[artenides]

Hi people,

Is there a way I can open the promote/demote tab for a specific guild member from lua?

I found this code snippet that opens the guild roster:

    if not CommunitiesFrame or not CommunitiesFrame:IsShown() then 
	  ToggleGuildFrame() 
    end 
    CommunitiesFrame:SetDisplayMode(COMMUNITIES_FRAME_DISPLAY_MODES.ROSTER)

If I click on a guild member (Bob) a small frame opens on the right in which I can promote/demote (Bob)
Is there a method I could open this frame for Bob from lua? Something like OpenGuildPromoteTab("Bob")?
