sharepoint server – Execute HTML in Column

I created a small CSOM application which read custom fields in project server Database and then store them in a sharepoint list, everything works fine except for the custom field multi lines of text

So if in my custom field, I store the following link , here the result I get in my sql DB < a href=””> ( I added the space at the begining)

and in my sharepoint list, I’m not able to render this url, so I have the url under this format < a href=””> and not
I tried to switch this column to rich text and Enhaced rich text but it is not worked

Any idea of how could I do that?

Ps: we are using Sharepoint 2016
