I'm running different tests with Playwright and I want to generate an Allure report. Also, I want to make different test run in order to see the history in the last html report generated.

Let's say I run 6 test in a single run, then I would type in my shell:

npx allure generate allure-results --clean -o allure-report

and then

npx open ./allure-report

This create me an allure-report folder with all the attachments I set on Playwright, like screenshots, videos, traces etc.. Then I add 2 more new test and run those 6 tests once again. Since the older folder with all the attachments would be overwritten, in order to see the history of these runs in the report, I copy the content of the old allure-report folder into allure-results. Then I can see all the history and all the attachments of the two new tests, but waht I can't see are the attachments of the first 6 tests, which are litterally there.. am I missing something?

If I didn't myself clear I would be happy to explain better my issue :)
