如何在gmail插件中添加按钮以触发我需要的功能？

Question

I created this script:

function buildAddOn(e) 
{
    var accessToken = e.messageMetadata.accessToken;
    GmailApp.setCurrentMessageAccessToken(accessToken);
    var messageId = e.messageMetadata.messageId;
    var message = GmailApp.getMessageById(messageId);
    var threadID = message.getThread();
    var threadLabels = message.getThread().getLabels();

    for (var i = 0; i < threadLabels.length; i++) 
    {
        var labelN =  threadLabels[i].getName();
        var label = GmailApp.getUserLabelByName(labelN);
        label.removeFromThread(threadID);
    }

    var newlabel = GmailApp.getUserLabelByName("TEST");
    newlabel.addToThread(threadID);
} 

It checks the labels of the thread I'm in at the moment and removing all and adding just one, the label: TEST

What I want is a button that when I press it, it triggers this script. I'm pretty new to code if there is a way to make it work would be very grateful for any help.

thank you

You can use the Card Service for creating buttons

• You can add your buttons to a ButtonSet
• Chose between different types of buttons, like eg the textButton
• Specify with setOnClickAction which action you want to run (eg call your function ).
