This was discussed in an earlier post - how to have windows open and close from the key fob on US vehicles that aren't set that way from Ford.
Previously it required using a windows app called FoCCCus, but that hasn't been updated in a bit and doesn't work with 2017+ models (and possibly 2016).
However the ForScan app for Windows can do it now and works across all years. There is still some trickery, you need a Bluetooth OBDII adapter, you need to register for the forscan forum and get an extended license key (free). But it worked well for me and had no errors.
Here is the forum post with the instructions:

Here is my video with the results:

If you don't want to bother with all of that, it seems many people have had luck simply asking their dealer to enable the option through their diagnostic software. It's called Global Open/Close.
