Forwarding received mail to Gmail so that the source address is not visible, how to simplify?

Question

gmail

Hello! I receive mail from different sources
on my Gmail html mailbox.
Basically, these are confirmations of orders for goods and services that are generated by stores and companies.
Most of them need to be sent to clients of the company I work for and which is an intermediary.
The task is to not see the sender's address on my Email.

Complicated. Editing in the browser debugger is not very convenient, it takes a long time and does not always work out beautifully, and sometimes it doesn’t work at all.
In general, it takes an insane amount of time than just taking a screenshot of an attachment.
But I would like to send it beautifully.
Nobody faced such a transfer?
