Please provide updated Thunderbolt NVM (46) on LVFS for XPS 15 9575 2-in-1

The Thunderbolt NVM available on LVFS (testing) has version 36 and was last updated 2018-10-24:

On the official Dell product support page a Windows firmware update utility is available for what seems to be version 46:

I would appreciate it if you could provide the newer version on LVFS ^^

Note: I have tried to extract the firmware from the above .exe, but I can't really make out anything that looks like a firmware (to me) in the files extracted by 7z. As such I sadly could not make use of the firmware-packager tool mentioned in other issues before. I am however inexperienced with the Dell / Windows .exe firmware update (utility) format, so it might be possible somehow nonetheless. If someone could point me in the right direction in that regard, that would be nice :)
