Installing mongodb on openSUSE Tumbleweed

I have to install a web service (usenet Nemo) that needs mongodb.
My distribution of choice is openSUSE Tumble weed.
None of the docs I found on the topic “mongodb suse” do works and the openSUSE repos are empty - I guesse it’s since the licence change.
Is there a way to install from official mongodb repositories?
If it’s not possible, what is the distro of choice to run mongodb?

As a first try, I installed mogodb and mongosh (I use aa64 arm processor) from tgz, but right now don’t yet have a working mongodb.
MongoNetworkError: connect ECONNREFUSED
mongod --dbpath /var/lib/mongo --logpath /var/log/mongodb/mongod.log --fork
Illegal instruction (core dumped)

but right now this is run from root account, not ideal. I don’t know yet what user I will have to use in fine.

Hi, as far as I can see openSuse is not supported, only SLES and then only when using x86_64 architecture.

yes, not officially supported, I know, but I guess it’s possible to install it manually, given some dependencies are met. I could also compile the source but if I can avoid it, the better
