Undocking ChatFrame?

[Zax]

Hello,

As often Shadowlands loose my chat windows configuration, I'm trying to write a little LUA script to rebuild my chat frames.
I'm creating a new chat frame, say for example "Guild" and I would like this new chat frame to be undocked. I have the following code:

local frame = FCF_OpenNewWindow("Guild")

FCF_UnDockFrame(frame)
frame:ClearAllPoints()
frame:SetPoint("TOPLEFT", ChatFrame1, "TOPRIGHT", 60, 0)--***
frame:SetWidth(ChatFrame1:GetWidth())
frame:SetHeight(ChatFrame1:GetHeight())
FCF_UpdateButtonSide(frame)-- ???
FCF_SavePositionAndDimensions(frame)

The chat frame is well created at the right of the ChatFrame1, but its tab stays docked.




Another question: is there a way to reset all chats without the confirmation alert showned by FCF_ResetAllWindows()?

Thank you.
