Hi Community 👋,
I'm working on a use case where I need to send rich HTML + Markdown content to a 1:1 Teams chat using Power Automate.
🔧 Flow I'm Using:
-
I take dynamic content in HTML + Markdown which includes:
-
Ordered lists
-
Tables
-
Headings
-
Bullet points (Nested)
-
Images
etc.
-

- The third image represents out of first converting html to text connector than that output is send which doesn't include markdown, newline other major html5 tag conversion.
If anyone has a sample using Task Module with Power Automate to display wide Adaptive Cards or HTML content, please share 🙏
Appreciate any guidance, code samples, workarounds, or alternate approaches!
Thanks in advance,
Vaibhav
