I don't know if we have any poetry experts here, but I'll shoot my shot: I'm trying to setup a plugin using the EDK that depends on a library that uses `extras`:

pip install 'elementary-data[snowflake]'
pip install 'elementary-data[bigquery]'
pip install 'elementary-data[redshift]'
pip install 'elementary-data[databricks]'

My goal would be that when people are using my extension, they can add the pip url as

pip_url: elementary-ext["bigquery"]

Currently, my idea is to create my own

extras

group that references to the elementary-data

extras

, and therefore only installs the required dependencies. To do so, I have currently setup my dependencies like this:

[tool.poetry.dependencies]
python = "<3.11,>=3.7"
structlog = "^21.2.0"
PyYAML = "^6.0.0"
pydantic = "^1.9.0"
click = "^8.1.3"
typer = "^0.6.1"
"meltano.edk"= {git = "<https://github.com/meltano/edk.git>", rev="main"}
importlib-resources = "^5.10.0"
elementary-data = {extras = ["bigquery", "snowflake", "redshift", "databricks"], version = "^0.6.4", optional=true}

where we get all dependencies from

elementary-data

and set them as optional. But when I try to reference them while creating my own

extras

, i.e.

[tool.poetry.extras]
bigquery = ["elementary-data["bigquery"]"]

I'm getting an error. My guess is it's because I should be creating my dependencies with extras this way. My question is: How could I structure my

pyproject.toml

so that it only installs the dependencies I need?
