Thank you.

Hello @zimuyou2,
those are https://squidfunk.github.io/mkdocs-material/conventions/ icons and are custom to Material for MkDocs documentation.
I'm not sure what you mean specifically with "button on agreement page", but in general this was asked many times before, closing and locking as duplicate:
