Can I save message text history?

I haven’t been able to find history files or other ways to save the text in a conversation. On a desktop, I can simply select/copy/paste the text on the screen. Is there a file somewhere? On the phone, I know how to save one message, but not the whole conversation. There is an app to do this with the regular Android message app, but it doesn’t apply to Jami.
Please help with saving phone text conversations. If there is a file somewhere, please tell me that too. Thank you.
