Adding new VLANs across trunks with etherchannels configured?

So I am bringing bringing over VLANs to the core. The interface is configured as a trunk, as well as the port channel.

If I add the VLANs to the physical trunk, will that not cause a spanning tree loop due to the Etherchannel configuration?

If I add the VLANs to the port channel on both sides, will that be sufficient enough to broadcast the VLANs? Or do I need to add them on the port channel and physical interface?

Int port-channel 8 Switchport trunk allowed vlan add 106-117

And/or

Int gi1/1 Switchport trunk allowed vlan add 106-117?

Thanks
