Call Hierarchy in Visual Studio Code

Question

I'm trying to find a "View the Call Hierarchy" feature in Visual Studio/VSCodium.

What I want to do is right-click on a method's name (or press a keyboard shortcut), and a new pane opens up, displaying all the methods that call the clicked method, and the call tree of this method.

I found that in Eclipse and PyCharm but I only found "Find all references" in VSCode.

EDIT: I want to do that in Python, but if a such feature exists for all languages, that would be nice.

This is currently (v1.33) a preview feature. See release notes re: call hierarchy.

A call hierarchy view shows all calls from or to a function and allows you to drill into callers of callers and calls of calls. The image below shows that function foo is being called by bar and bang, then bar is being called by bang and fib.

This is a preview feature and there aren't any extensions currently providing real data for it. However, if you are an extension author, we invite you to validate our proposed API. If you are interested, there is a sample extension for testing: https://github.com/jrieken/demo-callhierarchy.

There is already a bound command for this, editor.showCallHierarchy. You will have to see whether any python extension has support for this feature.

---------- Update -------------------

v1.43 Release notes: https://github.com/microsoft/vscode-docs/blob/vnext/release-notes/v1_43.md#call-hierarchy-support-for-javascript-and-typescript

In the v1.50 Insiders' Build is the ability to dismiss/exclude selected entries in the call heirarchy (possibly after you have reviewed that entry). See https://github.com/microsoft/vscode/issues/98155

Note the X dismiss button in the demo:
