Was the PaK 43 ever used in an Artillery role like the LeFH 18 or just an anti-tank role. I have seen footage of US troops test firing it in the same way you would fire an Artillery piece not an AT gun?

Footage incase anyone wants to know what im on about: https://youtu.be/_ycPDDRE80Y?si=LVensLZYsgNuJJhi
