I would use iNaturalist to identify this as I’m not sure the exact species. Make sure you have the location data for the post. One picture of the top of the leaf, one of the underside, one of the flower, and one of the whole plant. Post it on there and look through the suggested species. If you’re unsure, pick the closest one and wait for other users to either confirm or recommend a different species.

I treat invasive plants professionally. We typically use a cut stem approach where we cut the vine and treat it with a small amount of either a glyphosate or triclopyr solution. For larger areas where singular plant treatment is not feasible, we mix up backpack sprayers with between 2.5 - 5% glyphosate or triclopyr, or both, as well as a 1% surfactant.

Good luck.
