How to extend the size of a xfs?

I have 119Gb in sda2, but centos_template--centos7-root is only 27.8Gb, how can I increase it?

[root@runner~]# lsblk -o NAME,FSTYPE,LABEL,SIZE,MOUNTPOINTNAME                              FSTYPE      LABEL  SIZE MOUNTPOINTsda                                                  120G├─sda1                            xfs                  1G /boot└─sda2                            LVM2_member        119G├─centos_template--centos7-root xfs               27.8G /└─centos_template--centos7-swap swap               3.2G [SWAP]
