Hi Power Automate Team,
I've developed a flow activated by the MS Teams For a selected message action. Following activation, my goal is to ask for additional details from the user.

I understand this is achievable, as demonstrated by the Create a new Trello card from a message flow.

When attempting to construct a similar flow that includes requested fields, I encounter difficulties saving the flow due to these fields being mandatory.
As illustrated in the example below, I aim to prompt the user to enter the x-space-id, which is a dybamic list variable, in an MS Teams popup, similar to the Trello scenario.

How can I achieve this?
Thank you.
