Using HTML in Telegram bot

This is not a duplicated question. I want to use html codes in my telegram bot that is written by c#. I searched in SO but I did not find any answer. How to do that? I used TelegramBotSharp. Here is my code related to the part that I explained:

MessageTarget target = (MessageTarget)update.Chat ?? update.From;     
if(Text.StartsWith("Hello")) {
    bot.SendMessage(target, "Hello <a href='http://google.com'> dear</a>", true);
}

    from bs4 import BeautifulSoup



def for_telegrtam_html_text_normalizer(text):
    soup = BeautifulSoup(text, 'lxml')
    text = soup.get_text().replace('<', '≺').replace('>', '≻')
    to_set_tags = ['b', 'strong', 'i', 'em', 'u', 'ins', 's', 'strike', 'del', 'tg-spoiler', 'a', 'code', 'pre', 'blockquote', 'blockquote expandable', 'tg-emoji', ]
    for tag in to_set_tags:
        if tag == 'a':
            elems = soup.find_all(tag, href=True)
        else:
            elems = soup.find_all(tag)
        for elem in elems:
            if tag == 'a':
                text = text.replace(elem.text, f'<{tag} href="{elem["href"]}">{elem.text}</{tag}>')
            elif tag == 'tg-emoji':
                try:
                    text = text.replace(elem.text, f'<{tag} emoji-id="{elem["emoji-id"]}">{elem.text}</{tag}>')

                    pass
            elif tag == 'span':
                try:
                    cl_name = elem['class'][0]
                    if cl_name == "tg-spoiler":
                        text = text.replace(elem.text, f'<{tag} class="{cl_name}">{elem.text}</{tag}>')

If you need to format using html you need to set "parse_mode" as "html";

https://api.telegram.org/bot1328912345:BBCCDDExVAKD2GOEA1mXWfXfhQ_z8Y6rRh8/sendmessage?chat_id=12345678&amp;text=Sample message&amp;parse_mode=html)

As of now only following tags are supported by Bot:

<b>bold</b>, <strong>bold</strong>
<i>italic</i>, <em>italic</em>
<u>underline</u>, <ins>underline</ins>
<s>strikethrough</s>, <strike>strikethrough</strike>, <del>strikethrough</del>
<b>bold <i>italic bold <s>italic bold strikethrough</s> <u>underline italic bold</u></i> bold</b>
<a href="http://www.example.com/">inline URL</a>
<a href="tg://user?id=123456789">inline mention of a user</a>
<code>inline fixed-width code</code>
<pre>pre-formatted fixed-width code block</pre>
<pre><code class="language-python">pre-formatted fixed-width code block written in the Python programming language</code></pre>

Use the following syntax in your message:

*bold text*

_italic text_

[inline URL](http://www.example.com/)

[inline mention of a user](tg://user?id=123456789)

pre-formatted fixed-width code block

Note: Only the tags mentioned above are currently supported.

Tags must not be nested.

All <, > and & symbols that are not a part of a tag or an HTML entity must be replaced with the corresponding HTML entities (< with &lt;, > with &gt; and & with &amp;).

All numerical HTML entities are supported.

The API currently supports only the following named HTML entities: &lt;, &gt;, &amp; and &quot;.
