Is it possible for my BOT read messages of other LINE account?

I have a LINE bot named My-Bot. There is a LINE account Test-Account.

I wonder is there a way to let Test-Account login to My-Bot, then My-Bot can ask a permission to read messages, then Test-Account agree on that. After that My-Bot can read messages sent to Test-Account (via webhook)

From official API, I only know how to make My-Bot read messages sent to My-Bot (via webhook).
