Memberstack App missing action

Hello guys,

I'm trying to build an automation where I capture an html for submission and then I updated a value of a member inside the app 'Memberstack' memberstack.com but there are no actions for Memberstack only triggers.

Here are the options that I have in Zapier:

Is there a way to have this added, this is critical for a workflow I'm working on.

Thanks.
