MacOS application packaging

I have my own application, developed in Electron and C++. It is a bunch of files (binaries, images, etc). and work in MacOS too, but I need it to package it for MacOS. I developed it in Windows, and then ported to MacOS. My application already works if I start it from command line in MacOS. But my application does not start if I run the binary from Finder (it complains about security) Now I need to distribute it to the end users. I need you to write a (shell) script for me, which will get the directory where my application is located, and it will create a package for MacOS from it, if such thing is possible, or some other sort of single-file distributable container/installer. Maybe I am naive, maybe there are more things required, like some signing keys, registration at apple, etc ... I don't know. (I do not need to publish in apple store, by the way, only run it in Mac). If there are any further steps required to make a single re-distributable file/package/installer, you will kindly guide me through all steps, so as a result, I can have an Application (single file) which will be distributed to other MacOS users and it will work for them just by dragging the icon to their Application folder, or using similar fashion (I have no idea how Mac installs applications). My application also stores files in the current directory of the application. So you need to keep that in mind.
