Update field when due date is arrived #Flow

Hi Guys, I have one use case and can't find how to configure it. Probably you can help ? 

I have a field named "date of cession" . The team will put a date of cession (in the future. Eg : 01/01/2022) 

I have another field "available" which will have to switch to "unavailable" after the date of cession past. 

I have tought about creating a checkbox not visible "if due date<TODAY() = true" . And then, create a flow "if checkbox is true, assign the value unavailable". but I suppose that if the records is not updated by someone on that day, the flow won't be triggered. Any ideas ? #Flow Builder #Time Triggers #Record Triggered Flow

Thanks in advance :)
