The number of truncated buffers cannot be displayed

[HOU Haixiang]

Following the tutorial in the readme file, I config my vim. But my vim can not display the number of truncated buffers, buffet_left_trunc_icon, and buffet_right_trunc_icon. I don't know what I missed.

My vim looks like this.

The end is my vimrc. The font is MesloLGS Nerd Font.

I hope someone can tell why the number of truncated buffers cannot be displayed. Maybe I forgot to install some plugins.
Thanks.

Hi @hexid26! Can you please open enough buffers that do not actually all fit into the tabline and share a screenshot of that along with the actual :ls result?

[HOU Haixiang]

Sorry, @bagrat , I get the numbers when I open enough files. I get the screenshot here:

It works very well. Thank you very much.
