Sandboxed application can't communicate with browser extension

Right now I have this issue on Linux - Ubuntu 21.10. Here's the issue: when you need to add another account to the Linux desktop app (at least when you can't get into the first account and hence you had to create the second) you can't.

And now, my rant because I used to love you(1password) and talk you up to everyone and now you anger me greatly: I've been a 1Password user since Aug 2013 - when we could pay flat fees. When I got a new computer(frame.work - all the love) I found I can't have 1Password without putting all my passwords in the cloud. It scares me shitless to have the passwords that control my life in the cloud. (Yes my local is on the cloud. It's about layers. Someone is going to hack you one day whereas my computer is a no-one you'd have to target specifically.) I'm an engineer and I know too much. I can't even export my existing file and import it on the new computer because you made the app not work without logging into the subscription billing account. So I started the slow, painful process of moving to a browser-based password manager. It's also in the cloud and stores 3 text fields with 0 features, but it doesn't operate on a subscription model and I know their risk audit program is solid and 1password made me dependent on having a password manager. 6 months later I still have to keep going back to the old computer to get passwords. Yet I'm still being charged for 1password every month! I have 0 issue with paying for a software that made my life so easy. I have a real problem with the subscription-ization of modern life and the implications for IP and the model of corporate servitude it depends on. In any case, I went to login to the account that's charging me but apparently you can't reset the password and I (in best practice) made the account password different from my vault and now can't remember what super secret thing my brain came up with for it. So I went to make a new account. I can't log into it in the 1password app on Ubuntu because it still has the old account and no way to add a new one. I figured if I could get the app and the browser, where I'm logged in, to talk to each other the app could pick up the new account. But I ran into this issue. And writing this out I realize that making a new account to be able to cut off the credit card charge on a previous account makes 0 sense. But I'm still so mad that a great software company moved to a subscription model that I started going down this rabbit hole.

Could I please get confirmation that when I delete the original subscription account I made that the billing will also be turned off for it? I had a client not update the CC information in an AWS account after I handed the project over to them once and I don't want to go through that again.
