Kaputter touchscreen, how to control a cell phone without a USB OTG from the PC?

With my mobile phone (Huawei P9 lite) the touchscreen is broken, it does not support USB OTG, how can I bypass the USB access lock (the small button with which you first have to allow data access via USB), and then b access my phone, eg Whatsapp read news? Is that even possible?

You have the opportunity to access your phone via Teamviewer. If you have not yet set up Teamviewer on your phone, you can set it up with OTG.

"it does not support USB OTG"…

I did not see that. I'm sorry.
Then I would look around for software. Maybe you are lucky and then you can use this program to read out your phone without permission:

With this program you can also remotely control your smartphone, write sms etc.
