Removing USB OTG crashes phone and Restart needed

[jbafalcon100]

I have a Viofo Dashcam that records MP4 Video to a micro usb, to view recordings on my A40 I use an adapter between USB A and USB C plugging my phone into the C Phone socket  and the USB A into a SD Card reader.

So in line: A40>OTG Adapter lead>USB Card reader>Micro card 64gb.

I can view and remove the recordings on my PC (Win11) with eject. But that is not available on the A40 (As far as I know?) If I just unplug the chain the phone states I have removed the card unsafely and to restart the phone. Which is rather annoying! 

How do I remove the chain from the phone without having to restart it? My guess is it's to do with unmounting the card but if that is right where do I find how to do it?

Alternatively is there another option?

There should be an eject notification. We have vastly different phones but it should be a notification that lets you unmount it
