Immersive Reader on iPad Question

In the iPad version of Word immersive reader does not have (or I can’t find) the Grammar Options. I can get to the online editor in the Safari browser only by viewing the files in Onedrive, checking the radio button beside the doc and using the vertical ellipses that appear to open a menu, choose open and then open in browser.

O365 seems to want me to open word files in the iPad app.

If I am in teams I don’t have the option to open word docs in the browser.

The Grammar options look very useful but on iPad hard to get to.

A workaround for me is to screenshot the text in teams or word. Open office lens, scan the image and then send to immersive reader.

I am sure there must be a more sensible way to do this. I’d like to find it out before I suggest the workaround to my class!
