MySQL80 pkgs to SQLTools extension possible or not?

I am trying to create sql file with pkgs.mysql80. But I watched few youtube videos and vscode mysql connections(firebase studio and vscode are similar in using).
I get problems

  1. I installed mysql80 but only runs in terminal of firebase studio.
  2. I tried to add yua.sql. after installing pkgs.mysql80 only runs in terminal not in storing or running with project
  3. I tried to connect pkgs.mysql80 with SQLtools. I get error in connection. My rootname is rootsi. I attached the image below. I do not know what mistake i am doing. Please help.
  4. Is it not possible to connection mysql80 with SQLtools? Please share alternative way.
