First one: I ended up developing my own solution to run JavaScript automations for personal use. I decided to make it publicly available after more than a year of stable use, which is why I created the account to join the community. Just published it.
This one is not security related, but sure will be useful for many people who is more confortable with JavaScript than Python for complex automations. There will be more, but cleaning up code to make it publicly available (and minimally document it) takes time…
Any followup on this, anyway, please on the dedicated topic to avoid off-topic on this one.
