Currently I am looking for examples how to write an Office Add-In providing an UI with configurable options for the Add-In alone during installation. And sets them as roaming settings upon once consent is give (submit button).
There is this well-known API for Roaming Settings: https://dev.office.com/reference/add-ins/outlook/RoamingSettings. Plus an API for dialogues, see https://github.com/OfficeDev/office-js-docs-pr/blob/master/docs/develop/dialog-api-in-office-add-ins.md.
With these you can show an UI for configuring options. But my missing piece is how to display this during installation?
In other words: how can we ask the user for some parameters before finalising installation?
Any clues very welcome. Thanks!
