android - How to find which Graphic API, process is using?

Question

Some apps and games can use multiple graphic APIs like OpenGLES or Vulkan, each at one time, like PUBG? Mobile or CoD? Mobile that using OpenGLES and Vulkan but you can choose which api use during process runtime.

I tried lsof -p <pid> | grep -i -e gles -e vulkan and it gives me both *GLES.so and libvulkan.so which means they are not loaded at runtime but they are linked at compile time.

Question: How can I find out which API is the process using and calling its functions to renders the frames under the linux? (android is basically a linux based OS)
