Smartsheet Integration with M365

HI Smartsheet Team

We are finding ways to Integrate SS with M365 ,I have gone through he connectors articles given on the Help website. But couldn't find the M365 integration documents Instead I have found Dynamic M365.

My question is

1) Is there difference in Configuration Office M365 and Dynamic M365? are these two different application?

2) which are the point we should be mindful of before the Integration ?

3) Please share if there's any documentation regarding this
