How to get around error running snap app because it can't access $HOME/.inputrc

I understand why the error is happening. I understand snap is strict about this. However, I would expect there would be some way to manually tell snap that it's ok to access a particular file, or add a file to it's environment, or something like that to get around the error.

I'm working with the spark-client snap app. It's been working fine. I just added a .inputrc file to my home dir, and now it fails because inside spark-client.spark-shell, it being a REPL, there is code that sees the file, but can't read it. I notice that when running snap run --shell spark-client.spark-shell, the snap app can see all the files, but it can't read them (cat .inputrc -> permission denied). Is there some how I can get around this? Something like:

Give it access? snap connect {something with :personal-files}: can't because only the snap author can add plugs/slots?
Copy the file into the snap app? Can't because /snap/spark-client/current is a mounted, read-only file system.

I saw someone suggest running the command directly and not as a snap command. That would be ok with me. I found the command /snap/spark-client/current/opt/spark/bin/spark-shell but apparently something runs around it first because there are env vars it's expecting that aren't set, so I can't just run it directly. Is there a straightforward way to figure out exactly what is run as a snap app so I can run that not within snap?

You should be able to add files to `~/snap` and subsidiary directories.

I see that directory and am able to write to it. But doing so doesn't resolve the error. I tried putting it in ~/snap/spark-client/current/ and ~/snap/spark-client/current/home/jshellman/, but it did not resolve the error I'm seeing. It's looking for an absolute path `/home/jshellman/.inputrc`.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
