For example make a simple webserver that listens to requests on a certain route, those requests will contain the data, and simply add them to your database. It will be a nice learning experience ^_^ Anyways I have some time now so I might implement the telegram and discord webhooks soon.

You could use a good css selector instead

I recommend writing your own ^_^

Hey, I didn't add an ElementAction for this yet. Please open an issue on github about it and I will implement it soon.
In the meantime you can always use EXECUTEJS https://stackoverflow.com/questions/10911526/how-do-i-change-an-html-selected-option-using-javascript

Wait I don't understand. You said
The OpenBullet CLI is much slower compared to normal OpenBullet.
but then you said
I've tried the new and old versions, both are much slower than the CLI.
so which one is actually faster? The GUI or the CLI?

EXECUTEJS will replace any variable in the script using the usual syntax before actually executing it, so you can type for example

EXECUTEJS "console.log('<MYVAR>');"

and it will work

Also are you sure the website doesn't give this? It would match the error you're getting in OB.
(Verification Failed!): The signature or body of the extension has been corrupted and the signature does not verify. Chrome and other consumers should refuse to load this CRX.

If you can't upgrade it in any way, install a chrome build before 76 and the relative chromedriver.exe

As you can read on the website:
CRX2: A deprecated extension format. Support for most cases were removed in Chrome 76. The remaining cases were removed in Chrome 78.

You need to use a CRX3 version, CRX2 is not supported anymore

Are you sure you exported the crx correctly?
Also what's the need to write in all caps?
