greeks colonize East indies under Ptolemy Caesarion

Pls answer the follow up questions and like and share

what if Ptolemy Caesarion instead of believing Octavian into being lured back to Egypt
continues east along with all the Ptolemaic navy in Red sea to India
after learning of Golden Chersonese from traders in India restock and continue to those backward tribal lands( OTL Funan comes a century later) to establish a
New Ptolemaic Kingdom
He established Greek colonies on Malacca and Sunda straits taxing the bussling trade from and to China

will south east asia become Hellenized instead of indianized due to this ?

Wil Octavian start a man hunt and destroy this ?

will traders war with and destroy this ?
