Support for uploading a file to a Teams message

[TechDufus]

Is it possible to add a parameter -Attachment and point to a local file path to attach a file to the message?

Don't think incoming webhooks support sending files. That would be great - if you find out that it supports this we can work it out.

Dadgummit.. I should have done a search before making this issue. It looks like it's not supported yet.

I've found it too. But that's a very old thread and according to that Adaptive Cards are not supported either - yet here we are using Adaptive Cards in incoming webhook.
