How to make an array unique by object key?

How to make an array unique by object key?
I have dynamic checkboxes, whose id I put in the state.

In the format [checkBoxId]: e.target.value

And then I try to make a unique array from the received checked from the checkbox, but nothing comes out

[...new Map(
      myCheckboxes.map((item) => { // item {dfsd34534ftg: true} (dfsd34534ftg - id)
      const key = Object.keys(item);
      return [item[key], item];
   }),
).values()]

enter image description here

{response.map(({ id}, idx) => (
    <div key={id}>
       <Checkbox
          change={e => {
          setMyCheckboxes(prev => [
              ...prev,
              {
                [id]: e.target.checked,
              },
           ]);
          }}
          checked={myCheckboxes[idx]?.id}
       />
...
