BlueRigger Digital Optical Audio Splitter 1x3 Active

Helping my dad add a Bluetooth adapter(StarLink TV Streamer) to his primary TV ( Samsung 65 QN850 Series 8K UHD Neo QLED). So we currently have a optical cable coming from the Samsung TV to the Onkyo receiver( Onkyo TX-NR676) currently. This TV streamer will send the audio to my dad hearing aids.
So do I need to run a cable from the TV to the Splitter and from the Bluetooth adapter, then have the output from the Splitter go to the receiver? Or will that fail to send a signal back from the receiver to the TV?

Hopefully I have provided enough details I have also purchased Bluerigger cables to plug into the splitter since I read on Amazon some people were having having problems plugging the TOS cables into the splitter.
