Non strict string literal types

Hey everyone. I want to keep intellisense suggestions when defining something like this:

type SuggestedStrings = "cat" | "dog" | string;

type SuggestedStrings = "cat" | "dog" | string;

I want to be able to accept any other string but have suggestions when defining a variable. I am not sure what would be the right keyword to search for in this situation.

Using uppercase String seems to be working, though I am not sure if it is completely safe to do so in my situation with React stuff. It is only defined as a type, so I am assuming it wouldn't do some coersion in the background prayge

type SuggestedStrings = "cat" | "dog" | String;

type SuggestedStrings = "cat" | "dog" | String;
