How to update an existing task using Power Automate

I have a task already in asana and I wish to add a collaborator or assign the task when something happens through sharepoint. I have the task ID but when I look in power automate I do not see th option to assign or anything like that, just create.

Any way that I can do this easily?

We have a sharepoint list that has the asana items and wanted to assign from there and have it update to Asana.
