How to create type for reference object in TypeScript React app with useRef?

I create reference for object in TypeScript React app:

const inPropsRef = useRef({low: 10, high: 80, min: 0, max: 100})

And I need to type my reference object. I searched a lot of info, but everything is related to component reference type. I tried different ways, but every time get errors:

RefObject with generic:

// TS2339: Property 'low' does not exist on type 'Range | null'.interface Range {  low: number  high: number  min: number  max: number}const inPropsRef: RefObject<Range> = useRef({low: 10, high: 80, min: 0, max: 100})

Ref type with generic:

// TS2339: Property 'low' does not exist on type 'Range | null'.interface Range {  low: number  high: number  min: number  max: number}const inPropsRef: Ref<Range> = useRef({low: 10, high: 80, min: 0, max: 100})

Just interface:

// TS2339: Property 'current' does not exist on type 'Range'.interface Range {  low: number  high: number  min: number  max: number}const inPropsRef: Range = useRef({low: 10, high: 80, min: 0, max: 100})

Please can somebody help me how to write the correct type for the object reference.
