I'm trying to automate an interaction with a dynamic iframe using K6 Browser, but I'm facing difficulties when trying to click a button inside that iframe. The code I'm using is as follows:

const myFrame = 'iframe[src^="/"][src*="embedded=true"]';
      await page.waitForSelector(myFrame, {visible: true, timeout: 1000});
      const iframeElement = await page.$(myFrame);
      const iframeContent = await iframeElement.contentFrame();
      await iframeContent.click('//button[text()="Assinar"]');
      console.log(i)
      console.log(myFrame)

The iframe URL is dynamic and changes over time, but it follows a pattern where the URL starts with / and contains embedded=true.

I get the following errors:

WARN[0052] Unexpected DevTools server error: context canceled category="ExecutionContext:eval" elapsed="0 ms" source=browser

ERROR[0052] Uncaught (in promise) clicking on "//button[text()=\"Subscribe\"]": timed out after 30s

I tried using waitForSelector to wait for the iframe, but I still have issues.

Can anyone help me understand how I can handle dynamic iframe URL and click the button correctly inside it? What would be the best approach to do this, considering that the iframe URL is dynamic?
