FIWARE orion with atlas mongodb - mongodb-atlas

Question

Hello I'm trying to launch the FIWARE orion context broker using an atlas mongodb
mongodb+srv://<user>:****************#<domainid>.mongodb.net/<aut_db>
I have tried multiple variations of the docker run command but I never get the connection to success
trace:
$ docker run --name orion -p 1027:1026 fiware/orion:latest -dbhost "<domainid>.mongodb.net/<aut_db>?ssl=true&retryWrites=true&w=majority" -dbuser <user> -dbpwd U9NjLafksdv9mavW -logLevel DEBUG

Has someone know how I can configure orion context broker to connect to an mongo atlas?
EDIT: I have checked and I have access from that server to the mongo-db with the mongo shell

Orion currently supports only mongodb:// connection strings, built from the -db, -dbhost, -rplSet, -dbTimeout, -dbuser, -dbpwd, -dbAuthMech, -dbAuthDb, -dbSSL and -dbDisableRetryWrites CLI parameters(or default values, if omitted) as can be see in the source code.
There is an issue in the Orion repository with the aim of making this more flexible, allowing to provide the connection string directly overriding the above parameters.
While that issue comes (contributions welcome ;) you could hack the Orion source code cited above to build an specific version for you with support for mongo+srv:// connection strings.
