So I fiddled around with it a little, it is actually working, just requires a precise order of inputs, the Reason being that the "tick" characters, accents as they're originally called, are characters that never stand on their own but always above a letter.
Because of that, they are not printed immediately when you press the button but expect a letter input after, and if valid in combination produce the accented character, else they are printed in front of the second input UNLESS the second input is the space character, in which case the accent is printed on it's own.
Which is precisely what MS Teams is listening on.
This is important for the LAST Backtick only,
so when using inline Formatting you start your block with the backtick ` then input your code and then you press the Backtick character ONCE, followed by the space bar. This precise order of operations should produce the inline monospace (code) formatting.
For the multiline Version is even easier, you simply input the backtick THREE TIMES immediately followed by SPACE, this will produce a multiline codeblock that grows when you press enter. Enter twice in a row to leave the block, by the way.
Why this is not explained in detail on the MS tutorial website I have no idea, but this is how it works.
