Here's how it's currently called:

    const claimed = await contract.claimed(
      toChecksumAddress(evmAddress),
      '0x9c76bb33425ea109e9bddd5ff9e97d10de0dc8de5d123a7c288f8387a4b2ba2d', // merkleRoot
    );

Here's a test-case to add:

import { Arcade } from './Arcade';

describe('#Arcade', () => {
  describe('#isClaimed', () => {
    test('should return is claimed "true" for user who already claimed', async () => {
      const evmAddress = '0xE38a6F2045738Ea9F5Ad425E63537BA7679Eb82e';
      const isClaimed = await Arcade.isClaimed(evmAddress);
      expect(isClaimed).toBe(true);
    });

    test('should return is claimed "false" for user who hasn"t claimed', async () => {
      const evmAddress = '0xebc665ca518203db60203d10979ed1ebc30f190f';
      const isClaimed = await Arcade.isClaimed(evmAddress);
      expect(isClaimed).toBe(false);
    });
  });
});

Here is the bad vs good outputs
