How to file H4 EAD, Documents, Form i765 (New / Renewal Process)

Am in process of preparing my 1-765 form and i want to clarify about
Part 4: “Interpreter”
Part 5: “Preparer”

Am preparing my form on my own as am fluent in English and i don’t take any assistance, in that case can i leave both the section 4 and 5 as blank ?

And also can i leave Part:6 additional information also blank, incase of no information to add.

Please advise on the same
