@mlabouardy please check if the payloads are correct (you can do it in dashboard/utils/cloudAccountHelpers.ts).

Also, a few things are missing since I didn't know what to put there:

• Correct placeholder values resembling real API keys for MongoDB atlas and Scaleway
• Descriptions for Scaleway, Tencent, Linode, and MongoDB onboarding pages
