Not allowed to launch 'jnlps://host:port/cws/zbsl/zbsl.jnlp' because a user gesture is required.

Hey there! Since this is happening on both Edge and Chrome, it's likely a Chromium bug (or possibly intended behavior, though this does look like a bug to me as it's not respecting your exemption.)
It might be worth filing a new Chromium bug with your use case (https://bugs.chromium.org/p/chromium/issues/entry) as I only see a few open relating to gestures and not necessarily capturing this case.
