What is default name for configuration file?

Is it possible to set config in pyproject.toml?
I've tried:

[tool.pymarkdown]
mode.strict-config = true
log.level = "DEBUG"

But it doesn't look like it works

And one more question:
Maybe it would be best to support .markdownlint.json as defacto standard? Same file is being used for configuring the original markdownlint in Node.js

thinking about these this weekend. currently there is no default configuration file, but I have been thinking about the various defaults out there.
