How to find the address of the GetProcAddress function in kernel32.dll?

Question

Command line

I am writing a small training shellcode at the university to exploit a vulnerability. The executable is built with ASLR, so you have to mine everything right in the shell. Somehow I got the address of kernel32.dll, now we need to get the address of the GetProcAddress function in order to get everything else with its help. As I understand it, it must somehow be obtained from the export table. Knowledge is not enough, so I ask for your help.
Thanks in advance for all the replies!
