Save a fillable pdf to read only on iPad Pro

I have a fillable form on pdf. I have entered the inputs but I cannot figure out how I can save this on an iPad Pro as a read-only pdf as I don’t want my recipient to change the input fields on the file after I send it to them. I can do this on a Mac using print/save as pdf. I tried to look on the web and didn’t find any ways to do it on an iPad Pro. If you know, please share. Thanks!
