I have gdb running on cpp application process on remote machine, and accidenttly close terminal. How do i get into this gdb shell again?

$ pidof application 12345 $ pidof gdb 23456

gdb was started like "gdb --pid=12345" which is attached to process.

How do I get back into gdb shell from external shell. Is there any way like "enter-gdb-shell with pid 23456"
