Ability to specify custom headers for connecting to suwayomi server

Is your feature request related to a problem? Please describe.

I run a Suwayomi server in my homelab and expose it publically via Cloudflare and protect it via Cloudflare Access/Zero trust.
But since there's cloudflare in front of it now, all the client apps can't connect to it directly. Instead, i have to use the browser.

There's a feature in Cloudflare Access called "Service Token", in which we can specify a service token via headers and use that to authenticate.

Describe the solution you'd like
I want the ability to specify custom headers in addition to Server IP:PORT and basic auth.
This would provide me a secure way to connect to a suwayomi server which is hosted publically.

Describe alternatives you've considered
An alternative right now is to use a VPN like tailscale. But for that, i need to be connected to tailscale whenever i want to access my suwayomi which is not ideal.

Additional context
Cloudflare Service token docs: https://developers.cloudflare.com/cloudflare-one/identity/service-tokens/

Basically i need to specify these 2 in header

CF-Access-Client-Id: <CLIENT_ID>

CF-Access-Client-Secret: <CLIENT_SECRET>

Like this,

curl -H "CF-Access-Client-Id: <CLIENT_ID>" -H "CF-Access-Client-Secret: <CLIENT_SECRET>" https://app.example.com

There are various other apps that does this exact same thing for the purpose of connecting to services exposed via cloudflare tunnel and access. Like Lunasea ( https://github.com/JagandeepBrar/lunasea ).
