Description

Defining operations with multiple tags leads to duplicate export:

> tsc

src/apis/index.ts:3:1 - error TS2308: Module './AdminApi' has already exported a member named 'GetSelfServiceSettingsFlowRequest'. Consider explicitly re-exporting to resolve the ambiguity.

3 export * from './PublicApi';

Looks like setting
