can i use "AND" to where in connectOrCreate for prisma?

i want to make new holding. there are two cases.

1. there are no product, no account.
2. there are one product, account.

so i use connectOrCreate!. I want to find accountNum with userId and accountNumber so i use AND in where. but there are error.

Unknown arg AND in data.accountNum.connectOrCreate.where.AND for type AccountNumberWhereUniqueInput. Did you mean id? Available args

 const holding = await client.holding.create({
          data: {
            holdingNum,
            accountNum: {
              connectOrCreate: {
                where: { AND: [{ userId: loggedInUser.id }, { accountNumber }] },
                create: {
                  accountNumber,
                  user: {
                    connect: {
                      id: loggedInUser.id,
                    },
                  },
