Make initializer as static (#13506)

hyperxpro · web-flow · commit 1c7f0faac060 · 2023-07-24T14:45:19.000+02:00
Motivation:
I went through native transport and found that we don't explicitly mark
class initializers as `static`. We should mark them as `static`.

Modification:
Made initializers as `static`

Result:
Clean code and no more IDE warning pings.
