Could not find a declaration file for module '@colyseus/monitor'

[dortamiguel]

I can see that the code of this library is typed but when I import this library with vscode I get this error:

Could not find a declaration file for module '@colyseus/monitor'. '/Users/miguel/src/later/node_modules/@colyseus/monitor/lib/index.js' implicitly has an 'any' type.
  Try `npm install @types/colyseus__monitor` if it exists or add a new declaration (.d.ts) file containing `declare module 'colyseus__monitor';`

I tried to run "npm install @types/colyseus__monitor" but it didn't worked
