The returned `joinPromise` is resolved if the group is successfully joined, and rejected with an error if the join operation fails. The error message and the resolution time must _not_ depend on what interest groups a user is in, or any cross-origin browser state, apart from the results of the .well-known fetch, to avoid leaking any data across sites.

There is a complementary API `navigator.leaveAdInterestGroup(myGroup)` which looks only at `myGroup.name` and `myGroup.owner`. As with join calls, `leaveAdInterestGroup()` also returns a promise. As a special case to support in-ad UIs, invoking `navigator.leaveAdInterestGroup()` from inside an ad that is being targeted at a particular interest group will cause the browser to leave that group, irrespective of permission policies. Note that calling `navigator.leaveAdInterestGroup()` without arguments inside a component ad frame isn't supported inside a component ad frame until Chrome M120. Starting from Chrome M120, calling `navigator.leaveAdInterestGroup()` without arguments inside a component ad frame is supported. The ad component frame is required to be same-origin with the interest group owner for the leave to succeed, same as calling `leaveAdInterestGroup()` without arugments in a non-ad-component frame.

There is a related API `navigator.clearOriginJoinedAdInterestGroups(owner, [<groupNamesToKeep>])` that leaves all interest groups owned by `owner` that were joined on the current top-level frame's origin, and also returns a Promise. The `[<groupNamesToKeep>]` argument is an optional list of interest group names that will not be left, and if not present, it will act as if an empty array was passed. This method has no effect on joined interest groups owned by `owner` that were most recently joined on different top-level origins.
