How do I add the official work email signature format using Spark?

So I just got a new job just over a month ago. I have a work computer (Windows) that I use at work but like using my Mac when at home.

Currently, I have my email signature for work as the following:
Jonathan Davis
Special Education Teacher
Organization Name
Room #

They want to change it to stuff with my organization’s logo, my email, my work phone with extension, a disclaimer about sensitive information when sending emails, etc. Can I do this in Spark? There is an option of using without the organization logo. I’d rather not have to use Outlook for my work email but worst case scenario I could. Any help would be appreciated.

Spark has a good signature creator. Or you can use sth. like https://newoldstamp.com/.

I was able to figure it out. All good and working on mobile and the desktop app of Spark.
