 * https://learn.microsoft.com/en-us/microsoftteams/platform/resources/schema/manifest-schema#id
 * However, there are some older internal/hard-coded apps which violate this schema and use names like
 * com.microsoft.teamspace.tab.youtube. For compatibility with these legacy apps, we unfortunately cannot
 * securely and completely validate app ids as UUIDs. Based on this, the validation is limited to checking
 * for script tags, length, and non-printable characters. Validation will be updated in the future to ensure
 * the app id is a valid UUID as legacy apps update.
