Question I received a text message notification on my Smart TV ?

So here i am minding my own business on my phone, when I notice a sub box showed up on my TV. Me thinking its just a shut down prompt without looking I scroll along to press no so it doesn't turn off. I notice nothing happened when looking up the sub box said "are you sure you want to block this", with a message underneath saying " shut the **** up ya wh*re. Then without being able to see anything else the box closed by itself.
Is there a way to send text prompts to a TV through a phone?
I have looked through all my settings and there is nothing that shows about texts. I connected my own phone to the TV and its audio sharing only.
TV model: Toshiba smart TV 43LL3A63DB
I have tried everything to look at previous prompts but there is nothing suggesting that this can be done
