Slide out leak on 2022 micro 2108DS

[Audioi]

I have a pretty good water leak on the outside rear corner of the slide out. In a short time I can aquire a decent amount of rain on the floor under the seat cushion. There is no visible location of entry other than its coming from the floor/wall seam in the outside rear corner of the dinette. I assume its developing from the roof/ frame seal where the EternaBond tape is or should I start someplace else first??
