Share chat content across PCs

What version of Codex is running?

0.4.17

Which model were you using?

gpt-5-codex-medium/high

What platform is your computer?

win10 vscode

What steps can reproduce the bug?

I use local mode at two PC. I did some chat+code modify at PC1, and want to share it to PC2(PC2 has some chat PC1 do not have).
I believe there is a way that I can just manually copy the chat history log and paste to somewhere of PC2, so PC2 also has the same chat history.
or codex already has some synclization staff to do this job?

What is the expected behavior?

I did some chat+code modify at PC1, and want to share it to PC2(PC2 has some chat PC1 do not have).

What do you see instead?

at each PC, I only has the history when I run it locally.
