There’s many airports in MSFS that don’t match real world taxiway designators and thus using charts (even if available for that airport) might not match.
I use LittleNavMap, it reads the database from MSFS and when zooming in, it shows the same designators that MSFS ATC is using. Make sure to re-import the data after each MSFS update and each scenery you install or update.
You’ll have to find the route yourself, but it’s not that hard.
Here’s a video on how it is done with proper charts (but it works with LittleNavMap pretty similarly), though the audio is a bit bad. But you’ll get the point:
