You can create this yourself.

set <a href="call:123-456-7890">123-456-7890</a>

In a text object, set the html option on in the text object and place it anywhere you like.

It is not the software that recognises the number or makes it a tel nr. it is the phone that recognises this.

But on a desktop it will not work offcource.

Bet Regards,

 Yes but I don't think you would have any control over the text size?

Yes you can set text type's normaly.

But if it does not work on a mobile ( I did not test this) or one part does not, like colour, you can set it in the code, i can explain it here, but there are spaces on internet where it is already written.

see here: https://www.w3schools.com/html/html_links.asp

or here: http://www.echoecho.com/htmllinks02.htm

small example:

<a href="call:123-456-7890" style="color: rgb(0,255,0)"><font color="FF00CC">123</font>453</a>

...or to assign the LINK, ... choose the File or URL | Internet file  option and type in the URL address that gives its position on the Internet;  for example:

tel:0123456789     

tel:+440123456789        (+44    x en)

... or use the TAG <A> in Object HTML Code; for example:
<a style="font-size:22px;text-decoration:none;color:blue" href="tel:9876543210">Click Here To Call Support 987 654 3210</a>

(IT) - Per assegnare il COLLEGAMENTO, ... scegliere l'opzione  File o URL | File su Internet e digitare l'indirizzo (URL) che ne identifica la posizione in rete;   per esempio: tel:+390123456789

... oppure usi il TAG <A> in Oggetto Codice HTML; per esempio:
<a style="font-size:22px;text-decoration:none;color:blue" href="tel:9876543210">Click Here To Call Support 987 654 3210</a>
