"te no" grammar

Ive seen this quite a bit lately in reading. As an example, “話し合っての決定.” I didnt see anything for this on bunpro, but maybe im js stupid, i dunno. Has anyone else seen this and knows what it means? Normally I would js ask chatgpt but since i couldnt seem to find this on bunpro I thought it unwise to do so, as i couldnt double check it.

I haven’t studied it yet myself but I know there is at least ては grammar point here, so maybe that can help connect the understanding of te form + particles ては (JLPT N2) | Bunpro
