Hey Yani1! If you app has read access to Products, it should be able to see a Variant's metafields. Could you post some more info about the problem you are having? Info such as: Are you using the REST API or the GraphQL API?Could you paste the query ...

Thanks for letting us now! I fixed the typo in the docs, but it should take a bit before it's reflected in the webpage.Edit: The doc has been updated!
