How to use allure annotations in code directly?

Question

I am writing selenium based browser tests , I would like to implement @Step annotation inside page object models which are in src/java folder.

When doing that I am not able to use / import @Step annotation ( i have gradle ktls plugin installed )

This is code which is part of page object model under src/java

    @Step("Find flow based on file name : {fileName}")
    public DataTable findByFileName(String fileName) {
        selectedElement= dataTableElementList.stream()
                .filter(dataTableElement -> fileName.equals(dataTableElement.getFile_name()))
                .findFirst()
                .orElse(null);
        return this;
    }

Overall idea is to annotate all steps which are taken in page object model methods and then use it to create step-by-step annotated report.
