Currently working as Mulesoft developer but wants to switch to Web Development.

I am currently working as a software engineer on Mulesoft , but I want to switch to web development. I have 1 year of experience as a Mulesoft developer, but when I try to apply for a job as an experienced individual, they ask about work experience in a tech like React or Django. Since I was working on Mulesoft, I don't have experience in React or Django, so I have to say I have no experience in that, but I know React and Django. I have also worked on a project with them. What should I do?
