Correct settings for custom model in Github Copilot (Claude Opus 4.7)

I have an API key from Anthropic, but this only makes Opus 4.5 available as a model. I've found that I can manually add a model using `claude-opus-4-7` to use Opus 4.7, and with some random settings it seems to work. But I'm worried about which settings to actually use.
Does anybody know the correct settings for this model? Does it support "tool calling" and "image context"?

I tried to find out which settings are used for Opus 4.5 but couldn't find where those settings are stored. My custom model has an arrow to the right of its name that shows the attached screenshot, but the other models don't have this, so they obviously have some standard values stored somewhere.
