How to show buffer name like bufferline

[hiimnhan]

Hi Cosmic team,

I am a newbie to nvim and I found out that CosmicNvim is awesome(appreciate your work!!!).
I have a issue about open new file. It just show one by one file that it is not easy for me to follow which one I have opened. I think I prefer what bufferline provider

• this is current behavior
  

• what I prefer
  

Please tell me where I can config like this. Thank you
