First get a code editor for PC i recommend VSCode
For android you can use DroidEdit
Now the file you need to edit is debug_screen.json 
In the the debug_screen.json scroll down until you reach the "special_render" line in the code 
This is the only part you edit in the code and nothing else
In the debug_screen.json we add the following parts of code 
Now save your code and apply it like a resource pack
When your resource pack finally load you will see that your custom text is on the top where the beta text was
(Please note that this addon is not very stable and may crash your game)
Download the file from here ----> https://drive.google.com/file/d/1R-yPIiF_DZnHFbdcJWFOXNIK3pY5SC1W/view?usp=sharing
Enjoy!

Yeah since iOS is 1.2.10
and the files are different
See the version text on the bottom right corner? It says 1.2.11. How do I change that? Thanks!
