Show preview when asked to notify about a message

[igoradamenko]

Summary

When bot notifies me about the message, I see the link, but do not see the message, because there is no preview. It would be much better if there was a preview.

Describe alternatives you've considered

Eh, alternatives? Now I need to click on the message link to see the message. Then go back to the list of reminders and try to understand what was that link I clicked on.

Additional context

I use bot like this in MM Windows app:

/remind me "link to message" <time>

So, the bot notifies me about the link. This link leads to a message, but I do not see the message in the list of reminders.

Funny though, that when I mark a reminder as completed, it shows me the preview:

Top: a non-handled reminder, bottom: a reminder marked as completed.

If it's not my fault and there is a way to improve the bot, I'm ready to help. Just give me some context where to start.
