Complex Queries with Microsoft graph on SharePoint

[Chuksobi]

I have been trying to replicate my PowerApps function filter on Microsoft graph. Using the Graph API for SharePoint documentation. However, I am unable to group the various queries as seen below. I have not found any MS article on multiple queries. 

PowerApps Query =>      MeetingRoom=selectedRoom && ((ArrivalDateAndTime<=selectedStart && ArrivalEndDateAndTime>selectedStart) || ((ArrivalDateAndTime<selectedEnd && ArrivalEndDateAndTime>selectedEnd) || (ArrivalEndDateAndTime>selectedStart && ArrivalEndDateAndTime<=selectedEnd))

I have been able to do this that's the first part of the query and it works ( as seen below).

MeetingRoom eq 'General Board Room'

However, I have the rest of the query to complete and MS graph does not accept brackets '(' ')'

I have written what I believe the query should be like, with the brackets. 

and (

(fields/ArrivalDateAndTime<=2021-07-30T06:41:30Z and fields/ArrivalEndDateAndTime>2021-07-30T06:41:30Z)

or

(fields/ArrivalDateAndTime<2021-09-30T06:41:30Z and fields/ArrivalEndDateAndTime>2021-09-30T06:41:30Z)

or

(fields/ArrivalEndDateAndTime>2021-07-30T06:41:30Z and fields/ArrivalEndDateAndTime<=2021-09-30T06:41:30Z)

)

Graph Query 1=>  https://graph.microsoft.com/v1.0/sites/6e81a6f9-4953-4a8d-8ebf-a0764aa4aefe/lists/397b7365-5ff3-48d4-8b72-af2ad17165e9/items?$expand=fields&$filter=fields/MeetingRoom eq 'General Board Room' and fields/MeetingRoom eq 'Bar'

Please how do I group these queries?

I have gotten around this as the endpoint accepts brackets '(' ')' for multiple grouping. My query had an invalid character.
