Not an easy question. Chromuim by default has pre-made blobs of code from Google that cannot be opened/inspected. We don’t know if Microsoft has replaced or excised those blobs from Edge.
Ungoogled Chromium is a community project that replaces those blobs with code we can see amd audit, but again we don’t know if Microsoft builds off Ungoogled Chromium or just Chromium, because Edge itself is not open source.
