Approach after certificate completion?

Hi Guys,

I have completed all three levels of training with respect RPA developer’s foundation course.
I have completed my certification as well on 15th April(Legacy Certification). Also, I have completed two of the RPA challenges.
I have started solving questions on the forum as well.
Since I don’t have any experience of real-time projects, what should I do now to learn about real-time projects?
From designing to post-production support.
I am from a retail background and have no idea about the banking/insurance sector. I generally see people talking about invoices, pdf, and excel automation
I approached my client with RPA solution for automation desktop and mobile app but since, RPA is licensed based, they rather preferred open source tools like selenium and appium.
What should I do to learn how real-time projects are handled at companies?
