How to insert a long text using the sendKeys Protractor API? - protractor

Question

I have a long text 20 lines with HTML code that I need to use into a form test. For small texts I could use something like this:
browser.actions().mouseMove(element(by.id("field_bodytext")).sendKeys("BodyText <h2>Protractor</h2> Text1")).perform();
and it will work fine. But for 20 lines it does not. I have seen this information in Protractor API page, but can not see how to use it in my case:
http://www.protractortest.org/#/api?view=webdriver.WebElement.prototype.sendKeys
var form = driver.findElement(By.css('form'));
var element = form.findElement(By.css('input[type=file]'));
element.sendKeys('/path/to/file.txt');
form.submit();
There is an example for selenium that I do not see how to adapt: Selenium Webdriver enter multiline text in form without submitting it
This is the form field in Angular:
<div class="form-group">Wordhtml.com
<label class="form-control-label" jhiTranslate="jhipsterpressApp.post.bodytext" for="field_bodytext">Bodytext</label>
<textarea type="text" rows="10" cols="50" class="form-control" name="bodytext" id="field_bodytext"
[(ngModel)]="post.bodytext" required minlength="2" maxlength="65000">
<div [hidden]="!(editForm.controls.bodytext?.dirty && editForm.controls.bodytext?.invalid)">
<small class="form-text text-danger"
[hidden]="!editForm.controls.bodytext?.errors?.required" jhiTranslate="entity.validation.required">
This field is required.
</small>
<small class="form-text text-danger"
[hidden]="!editForm.controls.bodytext?.errors?.minlength" jhiTranslate="entity.validation.minlength" translateValues="{ min: 2 }">
This field is required to be at least 2 characters.
</small>
<small class="form-text text-danger"
[hidden]="!editForm.controls.bodytext?.errors?.maxlength" jhiTranslate="entity.validation.maxlength" translateValues="{ max: 65000 }">
This field cannot be longer than 65000 characters.
</small>
</div>
</textarea>
</div>
And the text to be inserted could be something like this:
<h2>What is JHipsterPress?</h2>
<ul>
<li>It is an open source and collaborative project made with Jhipster.</li>
<li>It is a live project that it is explained in its GitHub project. Explained? What do you mean? Whether you are a beginner that wants to find out an example about how to How to open access to the REST Api: or a more advance user who wants to see How to change DTOs to load attributes of not related entities: and see the actual code working, just visit the ReadMe file at GITHUB</li>
<li>And YES, you can use it for your own website.</li>
<li>At the same time JHipsterPress will try to create a community for Jhipster developers to join groups about different topics such as Websockets, Mapstruct, or anything you like.</li>
</ul>

Put the HTML in quotes `` as #lunin-roman is saying and then call it:
let htmltext = `<h2>What is JHipsterPress?</h2> and so on`;
element(by.id("field_bodytext")).sendKeys(htmltext);
and then use it in the element.sendKeys
