You can either interact with the "framework" through Github Issues or directly dispatching workflows if that's what you need.
For implementing this you need to use a self-hosted runner either with ARC or a standalone one just not to perform the scans from Github hosted runners. Moreover just not to install everytime the tools referenced you should include them either the base image of the runners of ARC or just to have them installed locally on the self-hosted standalone server.
