Add shared channel to mulitiple teams

Dear community,

I spend some time for searching this forum and the web for answering my question but unfortunately I did not found a suitable answer. Perhabs somebody of you could give me a hint.

I'm trying to create a shared channel and add this created channel to multiple teams by the graph api. Creation is not the problem but I haven't found anything for adding a shared channel to one or many teams. As I could see in the api reference there is only a way for create shared channels and unshare a shared channel with a team, but no way for sharing a channel to a team by the graph api.

Am I right or do I oversee something?

Thank you!
