New Teams app preview - support for slash commands is gone?

[TLCAdmin]

Has support for the (very useful) slash-commands been removed in the new Teams app? I see no mention of them in the preview documentation as far as what's a known issue, what's being removed, what's being worked on, etc.

I am appalled no one responded to this.
I just installed the new teams yesterday, and already reverted back. This is so disappointing. I don't even know if the interface is really that much faster, I am loosing so much time without the slash command that I certainly don't get more done on this new version, quite the contrary.

@gilles-h-ax Agreed. I went to use the Files command and found that it is gone along with the Help command and several others. I don't understand why this would be removed.

makes no sense since the new teams versions still has the limitations that these commands where (partially at least) adressing.
