You don't make clotted cream in an instant pot without a yogurt function, which is why you are not getting any search results. Making clotted cream involves heating cream to a constant warm temperature until the cream clots, which is similar to making yogurt. The yogurt mode on an instant pot heats to that relatively low temperature. If it doesn't have that mode it's going to pressure cook the cream and you won't get the result you want.
The steps above are not only wrong but possibly could damage an instant pot or pressure cooker. There are few recipes that would call for 4 hours of pressure cooking, and with the amount of water called for in these steps after 4 hours the cooker is likely to run dry, which is not a good thing. ChatGPG pulled generic instructions for an instant pot, then the time it takes for some other methods to make clotted cream and mashed them together to give you something not only wrong but possibly dangerous.
