EDIT not showing on the <RESOUCE>

I have follow the instruction on the website and found out the EDIT part not showing in the list page.

Here is my code.

<Resource name="Merchants" list={Merchants} options={{ label: 'store' }} icon={MerchantIcon} edit={MerchantEdit} create={MerchantCreate}  />

export const MerchantEdit = (props) => (
  <Edit {...props} title='Edit'>
    <SimpleForm>
      <DisabledInput label="Id" source="id"/>
      <TextField source="Translate[0].DisplayName" label="name"/>
      <FunctionField source="Rating" render={record => `${record.Rating / 100}`} label="rate"/>
      <TextField source="MonthlySales" label="sales"/>
    </SimpleForm>
  </Edit>
);

Did you add EditButton to Merchants?

export const Merchants = (props) => (
    <List {...props}>
        <Datagrid>
            <TextField source="id" />
             ...
            <EditButton />
        </Datagrid>
    </List>
);
