About the fact that you can not set "mention" when posting adaptive cards

[O365_JP_Support]

The Teams connector has the following actions related to adaptive cards:
"Post your own adaptive card as the Flow bot to a channel"
"Post your own adaptive card as the Flow bot to a user"
The <message> field of this action doesn't work for <at> </ at> tags, nor does it work for embedded in adaptive card JSON.
Please add "mentions" and implement the function to post an adaptive card.
