How we can post data to data entities OData endpoint in AX 7?

I have created 'TMSRoute' table data entities and  exposed it by setup public property is 'YES'.

Now I am able to get data in browser using OData endpoint.  But I not aware of how I can make POST request with Odata EndPoint or testing it with Client Rest API Third Party Tools.

I have referred this link for understanding OData endpoint in AX 7 : https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/data-entities/odata

Please help me out to understanding OData endpoint & correct me if anything I misunderstood. 

Please let me know if any example document is available for OData endpoint for POST or Put, Patch Request.

Thanks in advance.
