Odoo Development - Automated Actions in Odoo 13

Hello, thank you for your video. Is there also a way to use only python to create "Automations" we know from Odoo Studio? I cannot find any ressources about this topic.

music is annoying to be honest

I want to send mail automatically with the message written in log note dynamically to the foolowers of an opportunity....Is this possible?

Could be a useful video, if only the speaker would be audible. The sound is a nuisance!

Useful information, how do it on Sales Quotation
