How to inject mobx store into a stateless component

I am using mobx and react in a web application and I want to find a way to pass mobx store state to a stateless component. Below is my current component source code:

import React from 'react';
import Panel from './Panel';
import {inject, observer} from 'mobx-react';

@inject(allStores => ({
  form: allStores.store.form,
}))
@observer
export default class Creator extends React.Component {

  connect() {
    console.log(this.props.form);
  };

  render() {
    return (
      <Panel form={this.props.form} connect={this.connect.bind(this)}/>
    );
  }
};

How can I change it to be stateless? I tried below code but didn't work:

const Creator = ({form}) => {

  const connect = ()=>{
    console.log('xxxx,', form);
  }

  return (
    <Panel form={form} connect={connect}/>
  );
}

export default observer(Creator);

when I run above code, I got undefined value for form on the connect method. How can I inject the store into stateless component? I tried to use @inject on top of stateless component, but got a syntax error.

const Example = inject(
  'YOUR_STORE1',
  'YOUR_STORE2'
)(
  observer(({ YOUR_STORE1, YOUR_STORE2, OTHER_PROPS }) => {
    return (
        // Your Design
    )
  })
)

export default Example

A variant of @Tholle answer :

const Example = inject("myStore")(observer(({myStore, otherProp}) => {
  // ...
}));

inject returns a function that you can use on a observer functional component:

var Example = inject("myStore")(observer((props) => {
  // ...
}));
