The Save as, Open, or Upload dialog box that pops up within a web browser and prompts the user to browse and select one or more files to save as, open, or upload, can't be automated through the Web recorder or the Web automation actions in Microsoft Power Automate.
Web automation actions can interact with elements that exist within the HTML source code of the web page. However, the dialog box isn't part of the web page but comes from either the web browser application (Google Chrome, Firefox, Microsoft Edge, or Internet Explorer) or the Windows' File Explorer.
You can use either the Desktop recorder or the UI automation group of actions to interact with the elements within the web browser application or the Windows' File Explorer.
