git - How can I find where a git submodule was removed?

Question

Our project got a submodule fiosdk_kotlin added and now the most recent merge removed it but I can't find why its removal would be considered by git as a "trivial merge" as git instaweb puts it which as far as I understand means the same as git show yielding no chunks.

$ git show 6de05c
commit 6de05c46fb6dd19bf0d834290de8a3c36da22da3
Merge: 2b35c1a67 323b5e121

Now to explore what happened to the submodule:

$ git diff 6de05c46f...06ef8cfec -- fiosdk_kotlin
$ git diff 06ef8cfec...6de05c46f -- fiosdk_kotlin
diff --git a/fiosdk_kotlin b/fiosdk_kotlin
deleted file mode 160000
index 698b2b41f..000000000
--- a/fiosdk_kotlin
+++ /dev/null
@@ -1 +0,0 @@
-Subproject commit 698b2b41f4c7581bb4934da5d37f253d90963278

So there should be a commit somewhere on the second branch where the module was removed, right?

git log --all --full-history --patch -- .gitmodules should show me all additions or removals of submodules? It shows many commits (merge commits?) that don't show a patch at all. I can filter that down with -Sfiosdk_kotlin:

$ git log --all --full-history --patch -Sfiosdk_kotlin -- .gitmodules

    add fio as git submodule
    
    remove copied folders androidfioserializationprovider and fiosdk
    fix minSdk via main build.gradle
    restore String.isFioActor() in FIOToken

What the hack? It only ever gets added, yet it's gone?

Turns out, it's still there in .gitmodules but not pinned to any revision or something??:

$ cat .gitmodules 
[submodule "wallet-android-modularization-tools"]
    path = wallet-android-modularization-tools
    url = [e-mail]:mycelium-com/wallet-android-modularization-tools
[submodule "fiosdk_kotlin"]

 de7973e0781a8f6245b345999b6d2b7c6c45be6b wallet-android-modularization-tools (remotes/origin/api29submodule)

So as I don't get revisions to show in git log but in git diff, I tried this:

$ for h in $( git log --all --full-history --pretty=format:%h 1d6d2a~1..master ); do git show --oneline --patch $h -- fiosdk_kotlin | cat ; done

and again I see the submodule's addition but not its removal. What am I missing??
