How do i add another button on modal footer of antdesign?

I need to add another button on the Modal footer. How can i do it? In the documents you can only edit the ok and cancel buttons, but doesn't have a docs on how to add another button.

Use footer property of Modal which accepts an array of components.

      <Modal
        visible={true}
        footer={[
          <Button key="1">1</Button>,
          <Button key="2">2</Button>,
          <Button key="3" type="primary">
            3
          </Button>
        ]}
      >
        <p>Some contents...</p>
      </Modal>
