API Key storage location in Lua or other code

[b9Joker108]

I am a noob, using Termux to code, and so apologise in advance for my apparent and luminous stoopidity. I haven't really got into the swing of using this app, but it is a part of the bespoke nvim configuration I use, that was created by another. My Lua is quite rudimentary, but the nvim distribution I use, from my perspective, is quite advanced. The distro uses Lazy as a package manager. I wish to git push the current custom nvim distribution remotely to a public GitHub repository for safe keeping as I tinker. To do this, I feel I must first cleanse both the nvim customisation Lua sourcecode and any nested datastructures such as JSON, for example, of any secrets such as my API Key. I can't remember which way I entered the API Key for this app, or even if I have done so. But, if I have, where exactly should I look to find it in order to cleanse?

Any wisdom, practical and experiential knowledge, greatly appreciated.
