Samsung S7 Edge - Ant+ support

Hi, I bought a Samsung S7 Edge from the /e/foundation. Additionally I have ordered a fitness watch and want to use it with the Ant+ protocol which is supported by the Samsung phone. Do I need the Ant HAL service for this? I cannot see this service included on the phone. Do I have to install it by adb as system app? And from where can I get the apk in this case?
