Hello,
I have decent experience with bot development. I have worked with similar projects that included auto forwarding from channels. For your project, it can be made through by telegram user account because regular telegram bots can't read private channels\group. Also, you must be part of channel\group or be able to read it. Your real account does not require any actions except read as well. I have note about 6 condition, the bot I offer, could work with one TG account at a time. Changing accounts with this condition can be done manually. Job will be done on Python. Feel free to contact. Best regards.
