How do I enable camera and photo access in settings for apps on iPhone?

Hello, in many applications (which rely on photos or camera) I have a big problem with the message that appears "you did not allow the application to access your camera/photo gallery" "enable it in settings". When I go to settings I no longer have a tab for camera or photos, I simply do not have it. Can you fix this bug, please 🙏🥹
