concat string in array ts

I have a problem to solve, this problem is basically concat one value inside my array but the problem is my array won't accept a value i will concat inside the array below is my code.

interface SpecialtiesListProps {  specialtyId: number;  rqe: string;}const [id, setId] = useState<SpecialtiesListProps[]>([]);const [uf, setUf] = useState('');const handleChange = (value: string, SpecialtyId: number) => {    const newIdFilter = id.find((item) => item.specialtyId === SpecialtyId);    if (!newIdFilter) {      setId([...id, {specialtyId: SpecialtyId, rqe: value}]);    } else {      setId(        id.map((item) => {          if (item.specialtyId === SpecialtyId) {            return {specialtyId: Number(item.specialtyId), rqe: value};          } else {            return item;          }        }),      );      const newId = id.concat({uf})      setId(newId)    }      };

the error apear for me is this:

No overload matches this call.Overload 1 of 2, '(...items: ConcatArray[]): SpecialtiesListProps[]', gave the following error.Argument of type '{ uf: string; }' is not assignable to parameter of type 'ConcatArray'.Object literal may only specify known properties, and 'uf' does not exist in type 'ConcatArray'.Overload 2 of 2, '(...items: (SpecialtiesListProps | ConcatArray)[]): SpecialtiesListProps[]', gave the following error.Argument of type '{ uf: string; }' is not assignable to parameter of type 'SpecialtiesListProps | ConcatArray'.Object literal may only specify known properties, and 'uf' does not exist in type 'SpecialtiesListProps | ConcatArray'.ts(2769)
