not appear new resized LVM partition

I previously had 200GB of disk space and increased it to 250GB via ESXi for my guest machine. My machine is running CentOS 8. I tried to extend the logical volume at the path /dev/mapper/cl_mail-root, but when I try to check
via command DF

is show me old size not resized (text in bellow)
