How to summarize pdf files in edge mobile using bing ai

Question

I'm trying to summarize a pdf file that I opened in Edge using bing AI, but it can't do that. I have already given all permissions to this browser, even made it the default browser, but in any case it does not work. In the PC version of edge, bing can summarize PDF files without any problems, but in the mobile version it cannot. How can I make it work
