learning about physical volumes and logical volumes

I have RHEL8 on ESXi in my homelab. I increased the size of the vmdk by 35 GB. I rebooted the VM and now see this.

I am kind of stuck on how to get the root to expand over the other 35GB I increased the size of the vmdk by. Go ahead and make fun of me for not knowing but any help would be great. Thanks
