Need REST API for ComponentWatchers

Question

I can manually edit the "Component Watchers" but would like to do this via the API.

Documentation for the REST API does not appear to have an entry for componentWatchers.

Still need an API to update (PUT) a componentwatcher record. The above is only for a retrieve (GET).

https://community.atlassian.com/t5/Jira-questions/scriptrunner-post-function-to-add-watchers-based-on-component/qaq-p/208822 had at least a partial answer:

It looks like there is no public Java API, but there is public REST API. I can see, there are two endpoints which accept "project key" as a parameter

/rest/componentwatchers/1.0/groups/{projectkey}

/rest/componentwatchers/1.0/users/{projectkey}
Response of both endpoints contains this "section" of data $ curl --user 'user:passwd' --noproxy "*" "https://jira.example.com/rest/componentwatchers/1.0/groups/VLAB"
{
"projectKey": "VLAB",
"projectName": "VLAB",
"component": "00-RH_OpenShift",
"watchers": [
{
"watcherDatabaseId": "I_VLAB_OPENSHIFT",
"name": "I_VLAB_OPENSHIFT",
"type": "group"
}
