Container with a specific IP

Hi, I have a host with some containers. I mostly use one container for one website (LAMP). I have setup my containers with success. Now I need to create some more containers (LAMP as well) but those websites have their own IP. I have setup the IP on the host in the netplan configuration. I’m a bit lost with the LXC settings.
Should I create a new bridge? Can I use the existing bridge and add an IP to it? Should I just add the IP to the container?

I would recommend you to watch this video tutorial created by @Scott_T (who is also part of this community). Hope this helps : https://www.youtube.com/watch?v=2BSNV8Kz3Wg
