Use GitHub Discussions to ask questions, bring up ideas, or other general items. Issues are not the place for questions, and will either be converted to a discussion or closed.

This policy is in place to avoid bugs being drowned out in a pile of sensible suggestions for future enhancements and calls for help from people who forget to check back if they get it and so on.
