Fails to enable devtools or inject js into slack

[CodeF53]

Test Procedure

The following is the contents of test.js

setInterval(()=>{console.log("test")}, 100)

If it is successfully injected, we should see test logged to the console 10 times every second

To ensure the process runs correctly, I run the following to make sure slack has no background instances

taskkill -im slack.exe -f

Running the following command leads to slack successfully launching, with a perfect trace of what is being logged into the devtools console.

python -m electron_inject -d -t 600 -r ./test.js - C:\ProgramData\F53\slack\app-4.27.154\slack.exe

Pressing F12 in this new slack window does not open devtools, despite us having the -d argument

Running the /slackdevtools in any slack chat shows them manually.
Looking at the console we just opened, test is not being logged 10 times every second

Possibly relevant Info

Python 3.10.1
electron-inject 0.7
all installed python packages
Windows 10 Enterprise N build 19044.1826
Slack 4.27.154

I have a different OS on my laptop (Manjaro Linux).

Running the same procedure on it gives me a different result.

python -m electron_inject -d -t 600 -r /home/f53/Projects/SlackMod/inject.js - /usr/lib/slack/slack

• javascript is successfully injected
• f12 devtools still not enabled

system info

Python 3.10.5
electron-inject 0.7
all installed python packages
I still dont know my way around linux well enoiugh to give much more info

Python 3.8.5 x64
Electron-inject: 0.7
Windows 10 x64
Slack: Production 4.32.122 64-bit

Running
python -m electron_inject --enable-devtools-hotkeys -d -t 60 - c:\CoolDood\AppData\Local\slack\app-4.32.122\slack.exe

Does not enable dev tools. The terminal has some logging info going on but that is.

Yep, doesn't work with Slack at all. Script is not injected, keys don't work.

Python 3.10.10
electron-inject 0.7
Manjaro
Slack 4.32.122

Probable cause:

[__init__.py -               inject() ][    INFO] injecting hotkeys script into 54D02EB3556E5B88E6981F034B2CB656

Edit:

running it like this seems to somewhat work - at least the script (not the keys).

python -m electron_inject -d -t 60 -r test.js - /usr/bin/slack '--remote-allow-origins=*' 2>&1 | tee ei_slack.log
