Apostles journey to the Israelites will be added to the Book of Acts. " What do you base this on?

This is a very shorten answer, because some do not accept what the scriptures say, but go by what someone tells them.

First and foremost, what is the name of the Book:  the Acts of the Apostles.  This is very minor.  We know Peter has minor parts and John has a very minor part in the Book of Acts.

Do we know where the 12 Apostles went and what were their instructions from Jesus.  Jesus commissioned the Apostles to only go to the lost sheep of the house of Israel

(Mat 10:5-6 KJV)  These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: {6} But go rather to the lost sheep of the house of Israel.

Paul was commissioned to bear the gospel to the Gentiles. kings and the children of Israel. 

(Acts 9:15 KJV)  But the Lord said unto him, Go thy way: for he is a chosen vessel unto me, to bear my name before the Gentiles, and kings, and the children of Israel:

We notice Paul was to go to the Gentiles, kings and children of Israel.  Acts cover Gentiles, kings, but not children of Israel.  You noticed that Luke doesn’t finish the life of Paul after imprisonment.

I have already covered that Josephus know where the children of Israel were located when he wrote his works.  Surprising, how individuals believe the works of Josephus, but do not believe this.

James epistle was to the 12 tribes of Israel. He knew where they were Have you notice that the Book of James ends abruptly, like the book of Acts, without the normal salutation and amen.

(James 1:1 NIV)  James, a servant of God and of the Lord Jesus Christ, To the twelve tribes scattered among the nations: Greetings.  Paul never spoke in these parts except for the southern part of Asia.  He was not allowed to go north Asia.

Notice Peter letter was address to strangers scattered.  Peter was to go to children of Israel, not Gentiles.  He would not have called Jews strangers.

(1 Pet 1:1 NIV)  Peter, an apostle of Jesus Christ, To God's elect, strangers in the world, scattered throughout Pontus, Galatia, Cappadocia, Asia and Bithynia,

Remember, the Apostles were to go to the the lost sheep of the house of Israel.  There was a Greek and Latin works, called Ecclesiasticae Historiae.  It was translated into English, called Antiquities Apostolicae, by William Cave.  This work covers the Apostles and where they went and a very interesting read.  I think you would enjoy it.    Out of words
