Failed to connect to erc-tls with sasl connection

Hello guys,

i am using vanilla emacs and I am fighting to make erc works with sasl connection.
As I want to connect to the Libera server, I checked this page but still failed to connect.
Can someone can help me solve this, please?

Did you have a look at my last try?

Alternatively, you can try this link
It works for me with a little twist in my .ercrc.el
Good luck.
