I want that when a Miro frame/board is inserted in the page, all users who have minimum view right to that page should be able to view the board/frame, zoom in and out, etc. regardless of their access rights in MIRO. Any changes later in the MIRO board should reflect in this XWiki page as well (most likely in real-time).
As Thomas said, this can be achieved through the HTML macro.
I just tried it out, and it works flawlessly, here’s a little video demo: https://i.imgur.com/yyrX4lv.mp4
The instructions are as follows: In Miro
Open the board you want to share
Click on the export icon in the top left (to the right of the 3 dots menu)
Click on “Embed” (make sure that “Anyone with the link” is set to “viewer”)
Click on “Copy code”
In XWiki
Go to the page you want to insert the board in
Edit the page
Add an HTML macro to the page
Paste what you copied from Miro into the HTML Macro
Save the page
Now every user that visits the page will now be able to look at the Miro Board, pan around, zoom in and out, and see changes live.
(It took more for me to find a way to add the video to the forum reply than it took for me to get Miro to work inside xwiki )
