What is the poetry equivalent of installing extras / or the equivalent of the following pip install command:
`pip install python-jose[cryptography]`
`poetry install python-jose[cryptography]` gives `no matches found: python-jose[cryptography]`
In the [docs](https://python-poetry.org/docs/cli/#install), I see the `-E` argument but the sample code seems like it's only installing extras:
poetry install --extras "mysql pgsql"
poetry install -E mysql -E pgsql
...and the "main package" should already be in pyproject.toml.
The link to `Extras` where it says
> (See [Extras](https://python-poetry.org/docs/cli/#extras) for more info)
seems to be broken.
`poetry add -E [extra package] [main package]`
So in the case of `python-jose[cryptography]`:
`poetry add -E cryptography python-jose`
It's currently not document in the `add` section of the docs, but I assume the argument works the same as it is used in `install` so perhaps you can add multiple extras by doing:
`poetry add --extras "[extra1 extra2]" [main package]`
