Text message with string and unique url

We're trying to send out unique links to each contact as a text message from flow action - something like

"Hi John Doe, Please fill out Survey by clicking the below link

{Contact Specific Unique Link}"

I don't see an option to send the combination of text message & a contact specific unique link embedded in the text message. Did anyone try to achieve this? Please let me know as this is blocking our text message initiative to be able to send text + Unique links. Thanks!
