@Adela, it's a scary task starting off with any automation framework, specially if you are a manual tester with limited coding skills.
Robot is a good choice for that, however it takes some time and effort to get started.
The documentation is very detailed, so are many Youtube and Udemy courses! unless you can get someone to jump onto a call with you to jump straight to your project implentation.
Step one would be to follow a beginner robot course in yourtube, 3 to 5 days (this will be SeleniumLibrary)
Then read up on "relative xpath and xpath queries"
Then try using the Robotframework-browser library
