In a Web Component How to show tooltip & hide tooltip when clicking outside or when another tooltip clicked

I have this Web Component that has cards with tooltips.

I am trying to accomplish 3 things. I am trying use Vanilla Javascript vs jQuery or other libraries.

1. Show when a button is clicked then hide if button is clicked again. This is currently working.

2. Hide when clicked outside of button. I tried selecting the document then comparing clicked element with the element I want to target, having trouble with targeting.

3. Only show 1 tooltip at a time so if 1 is open then you click another only the second one shows. Not sure how to approach this.

Here is what I have so far.

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

class BuildABox extends HTMLElement {
  constructor() {
    super();
    this.querySelectorAll('[data-tooltip]').forEach((button) =>
      button.addEventListener('click', this.toggleTooltip.bind(this))
    );
  }

  toggleTooltip(e) {
    e.preventDefault();
    const toolTip = e.currentTarget.lastChild.previousSibling;
    toolTip.classList.toggle('tw-invisible');
  }
}

customElements.define('build-a-box', BuildABox);

You don't want to create dependencies, thus keep as much of the logic inside the Web Component

Using shadowDOM here because it keeps the Web Component small
and you can style with global CSS using ::part

Key concept: <my-button tooltip>
The tooltip attribute determines of it is visible, or not

I whacked in additional styling to show more styling options.
For deep-deep-details on <slot> and ::slotted read: https://stackoverflow.com/questions/61626493/slotted-css-selector-for-nested-children-in-shadowdom-slot/61631668#61631668

To expound upon my prior comments which I deleted; I updated your code slightly and added some CSS to show it clearly here. I have a data element to choose a target and then use that in the click handler.

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

class BuildABox extends HTMLElement {
  constructor() {
    super();
    this.querySelectorAll('[data-tooltip-target]').forEach((button) => {
      button.addEventListener('click', this.toggleTooltip.bind(this))
    });
  }

  toggleTooltip(e) {
    e.preventDefault();
    const mytarget = e.currentTarget.dataset.tooltipTarget;
    const toolTip = e.currentTarget.querySelector(`[data-tooltip="${mytarget}"]`);
    toolTip.classList.toggle('tw-invisible');
  }
}

customElements.define('build-a-box', BuildABox);

<!-- language: lang-css -->

.tw-invisible {
  display: none;
}

.tooltip-text {
  color: blue;
  font-size: 1.5rem;
}
