Can I create a custom tip button for my own website?

Is it possible to adapt brave-site-specific-scripts code to create a custom tip button for my own website?

Let's say I put the port.postMessage call, from github/tipping.ts, on a button on my website:

brave-site-specific-scripts/scripts/brave_rewards/publisher/github/tipping.ts

Lines 36 to 50 in 6f59813

	port.postMessage({
	type: 'TipUser',
	mediaType: types.mediaType,
	data: {
	url: profileUrl,
	publisherKey,
	publisherName,
	publisherScreenName,
	favIconUrl: mediaMetaData.user.favIconUrl,
	postId: mediaMetaData.post.id,
	postTimestamp: mediaMetaData.post.timestamp,
	postText: mediaMetaData.post.text
	}
	})
	}

And replace the variables with my publisher data (plus other JS code like port), will it work?

I'm thinking to create a WordPress plugin so people can add a "Donate with Brave" button on their pages.

PS: Sorry in advance if this is not the right place for this kind of question. Let me know if there is a better place to ask this.

Interesting, I get a Could not establish connection. Receiving end does not exist. when I try to connect to Brave extension:

const braveExtensionId = 'mnojpmjdmbbfmejpflffifhffcmidifd'
chrome.runtime.sendMessage(
  braveExtensionId, 
  { type: 'SupportsGreaselion' }, 
  (response) => console.log(chrome.runtime.lastError)
)

I get the same error if I try to connect to the Rewards extension with:

const braveRewardsExtensionId = 'jidkidbbcafjabdphckchenhfomhnfma'
chrome.runtime.connect(
  braveRewardsExtensionId, 
  { name: 'Greaselion' }
)

As this connection is necessary for creating the port object, I think I won't be able to create the custom tip button.

I wonder if there's a limitation preventing access to the Brave extension outside "brave-site-specific-scripts" or if is just me doing something wrong.
