Mark SMS as read

Hi everyone,

I have a webhook tied to an SMS event where I receive MMS and SMS and sends an automated response to each person contacting us.

I'm having issues at the time of receiving multiple SMS/MMS from the same phone number, I don't want to send multiple confirmation messages, just one. I've managed to do that in my code by checking the time difference between the last text received and the current text.

My problem being, after sending that initial automated response, I have a rule as to not reply to any text from the same phone number that is incoming within a 5 minute timeframe, but those texts are still being shown as unread on the dialpad app. They're only shown as read after the reply SMS is sent back to the customer.

How could I mark an inbound SMS as read without having to reply to it?

I'd appreciate any help on this, thank you.
