• partnership
• subscription Subscription e2e test #1103
• therapy Already enough covered with the existing therapy-usage tests
• welcome Welcome e2e tests #1092
• [slug] Already enough covered with the existing activities and grounding-exercises tests
• 404 Already covered but skipped due to an issue in the dev server
• 500 500 e2e tests #1111
• about-our-courses About-our-courses e2e tests #1109

Could you tell me how I could access to /partnership/badoo or /partnership/bumble or /partnership/fruitz?

Could you tell me how I could access to properly call /api/preview, I have seen it is expecting an slug parameter as well as a secret one that should be NEXT_PUBLIC_STORYBLOK_TOKEN value. I have tried using chat as the slug value but I am getting the following page:

Thanks!
