Get limited data from emails


I have this get email tool in my n8n workflow, however, I get a lot of data for each email, how can I get just the relevant fields from the email such assubject, from, to, date, textPlain (or text) and possibly snippet?

I need to pass these emails through LLM Model, which run out of token limit everytime as the email data is quite huge, so how can I limit that information to the most relevant by making changes in the getemail tool?
