Do i need cash bhat to enter thailand, and can i come from Kazakhstan as an indian

So i am an indian passport holder while studying in Kazakhstan with a student visa

I am going to india while staying 4 days in bangkok

The main issue i think will be that at immigration they ask if you have thai bhat in cash on you or not i have enough INR in my account but there is either no way to get thai bhat in Kazakhstan or the rates will be so scuffed

I am planning to withdraw at the airport so they will allow me with just INR ?

I have booked the hotels for full stay from aghoda

And i will fill the declaration form but what should i fill in it i am indian

citizen but coming from Kazakhstan

If you guys have any other tips please let me know

Also if you guys think i should worry about something else tell me please
