How to install chromium on ios device like iPhone or iPad?

[Satoshi Goto]

Hi,

I'm trying to install chromium into iphone, but there is no such an explanation here.
https://chromium.googlesource.com/chromium/src/+/lkcr/docs/ios/build_instructions.md

do you know how we can install Chromium.app into iphone?
all I did was adding the below into args.gn and build it successfully with ninja -C out/Release-iphoneos gn_all.

ios_code_signing_identity = "ABCDEXXXXXXXX"
ios_app_bundle_id_prefix = "com.mydomain"

and tried to create ipa manually, and installed via itune, but cannot launch Chromium app because it says "unable to install Chromium".

here is what I have done.
$ mkdir -p Payload && cd Payload
$ cp -R ../src/out/Release-iphoneos/Chromium.app .
$ cd .. && zip -o -r -y Chromium.ipa Payload/
installed via itune
