Need inputs on usage of chromium zygote

[vishnu vardhan reddy.p Reddy]

Hi, I am trying to launch chromium zygote process with a different entry point than the exe that launches the browser. I was able to it successfully but facing issues when enabling the sandboxing. 

https://source.chromium.org/chromium/chromium/src/+/main:sandbox/policy/linux/sandbox_linux.cc;l=574;drc=317154f193cfe466e41fb1ad2c4a2717a3197442

Sandboxing code checks if the process IsSingleThreaded() in my case which is not. I cannot get rid of the other threads. Any inputs on how to enable sandbox in this case?
