Door seal question

I noticed this seal pulled away a little. It is, I assume, an outer door seal, that seals the gap between the front door and the back door. Adhesive adheres it to the front of the rear door. I must have pulled it off getting in the truck. I could probably fix it with some double-sided thin 3M tape but I was curious if this single part is available. Parts manuals seem to show it as being apart of an assembly going all the way around the way around but I think I'm looking at the wrong thing. Any help is appreciated

 

Can't you simply push it back on the pinch weld? I'll need to look at mine.

 

It’s held on by adhesive. No clips or creases or anything
