Integration owners are listed with their GitHub handles in the codeowners field of the manifest of an integration. Hassfest generates the CODEOWNERS file of Home Assistant Core from those lists, which GitHub uses to ask them for reviews. When an issue gets the label of their integration, the bot mentions them.

The code calls them code owners: the codeowners field, the CODEOWNERS file, and labels like by-code-owner. In text about integrations, say integration owner. "Code owner" still fits a CODEOWNERS file of a repository that is not about integrations, like the teams that own parts of the frontend.
