Hey @GoulielmosFloros! Thanks for this PR.

If you have set Lit as a peer dependency, then you:

1. Can remove it from the dependencies.
2. Don't have to modify the vite file as peer dependencies are never included in the final build.

May you update those things, please?

Hi @GoulielmosFloros! Coming back to this after a long time.

We have already taken a decision for this specific Lit warning. It is documented here.

Thanks!
