Configuration option to only manually open signal rooms/dms

[jakobw123]

I've been playing around with a Matrix Homeserver setup lately, via the Matrix Docker Ansible Deploy bundle. As this is my first project regarding the Matrix world, i'm fairly new to the topic.
I've also added some features such as this Signal Bridge as well as the WhatsApp Bridge.
I would like to be able to only manually sync rooms/dms between other ecosystems, like Signal, WhatsApp, and Matrix.
For WhatsApp i've been able to achieve this by turning off the backfill and making use of the open <room id> command. Room ids can be accessed with the list <contacts/groups> command.

I would like to configure my Signal Bridge in similar way. Unfortunately, i couldn't find any commands to manually sync/open rooms/dms from Signal to Matrix.

• Have i missed any commands already available, which achieve manual room openings?
• If not, are there any plans to add those type of features to newer versions of this Signal Bridge?
• Or does anyone added such features to their own project and could give me a short hint on how to add those to my project?

In addition i would like to prevent the Signal Bridge from syncing rooms with Matrix when new messages are received in the signal-sided room (after linking my Signal account with the Signal Bridge Bot).

• Are there any settings currently available to prevent auto sync on incoming message events?
