Is this memory card compatible with the GoPro Hero 13?

Yes, the memory card is compatible with the GoPro Hero 13.

The memory card you mentioned is a microSDXC format, while the Nikon Z50 requires an SD card. The camera supports SD, SDHC and SDXC cards in UHS-I format. Since the memory card you have is a microSDXC format, you will need an adapter to use it in an SD card slot. However, the adapter is included [Product properties]. Therefore, the card could theoretically work if the adapter is used correctly, but it is important to note that the camera is specifically designed for SD cards.
