Flow numbers and Markdown

[k_b]

I have asked this before, but can’t find the thread:
I have Markdown checked, so I can make parts of a flow heading italic. What is the exact way to also include a flow number? Example:

45. Aria I know that my redeemer liveth

The aria number at the beginning vanishes, unless I input something with backlash \
but how exactly?
Thank you for help again.

[edit] I found it (it’s 45\.):

Number in Flow Title missing

Either uncheck Resolve Markdown formatting for text tokens at the bottom of the Project Info dialog or replace “6.” with “6\.”

Project title starting with number doesn't work

You can also type 1\.. Or you can turn off the option at the bottom of the Project Info dialog to use Markdown formatting.

So it is a backlash before the dot.
