Macbook pro 13" 2022 USB C connections

I recently bought a MacBook Pro, the 13" M2 2022 with 2x USB-C connections.

Connected to this is my Samsung Monitor via usb c and my sound interface -UAdio Apollo Twin X- via thunderbolt3 cable to the 2nd and last usb c connection. This works perfectly until I want to connect a third USB-C device, for example my Samsung SSD. For this I purchased a USB-C hub from Sitecom (USB-C to 4x USB-C). However, my sound interface does not work on this and neither does my Samsung monitor when I connect one of the 2 to the hub. I can connect all other usb -c devices to the hub (camera, ssd, phone etc), but then I am short of a port for either my monitor or my sound interface card. How can I solve this?
