Should I put sdk on single play?

It’s a single play game developed by Unity.
The server exists.

Do I need to add sdk when I build?

I ask you questions because I don’t understand the docs. I’m sorry.

SDKs are often used for integrating third-party services, APIs, or platforms into your game, such as analytics, advertising, or multiplayer functionalities.

Hi! Typically, you don’t need an SDK in the build for a single-player game. SDKs are more for multiplayer, analytics, or specific integrations. If the documentation is confusing, no worries, just concentrate on your single-player build for now.
